For three years, Yemen, the Arab world's poorest country, has been wracked by a bloody war between the Houthi rebels and supporters of Yemen's internationally recognised government.

The Houthis and the Yemeni government have battled on-and-off since 2004, but much of the fighting was confined to the Houthis' stronghold, northern Yemen's impoverished Saada province.

In September 2014, the Houthis took control of Yemen's capital, Sanaa, and proceeded to push southwards towards the country's second-biggest city, Aden. In response to the Houthis' advances, a coalition of Arab states launched a military campaign in 2015 to defeat the Houthis and restore Yemen's government.

Here are some key facts about Yemen's complex war:

As of March 26, 2018, at least 10,000 Yemenis had been killed by the fighting, with more than 40,000 casualties overall.

Getting accurate information on the death toll is difficult, but Save The Children estimated at least 50,000 children died in 2017, an average of 130 every day.

The United Nations High Commissioner for Human Rights has estimated that Saudi-led coalition air strikes caused almost two-thirds of reported civilian deaths, while the Houthis have been accused of causing mass civilian casualties due to their siege of Taiz, Yemen's third-largest city.

Millions of Yemenis have been displaced.

The UN office for the coordination of humanitarian affairs (OCHA) estimates that more than 3 million Yemenis have fled their homes to elsewhere in the country, and 280,000 have sought asylum in other countries, including Djibouti and Somalia. As reported by Al Jazeera, internally displaced Yemenis often must cope with a lack of food and inadequate shelter. Many Yemenis who have not fled are also suffering, especially those in need of healthcare.

Many foreign countries are involved in Yemen's war.

In 2015, Saudi Arabia formed a coalition of Arab states to defeat the Houthis in Yemen. The coalition includes Kuwait, the United Arab Emirates, Bahrain, Egypt, Morocco, Jordan, Sudan and Senegal. Several of these countries have sent troops to fight on the ground in Yemen, while others have only carried out air strikes.

The United States government regularly launches air strikes on al-Qaeda and Islamic State of Iraq and the Levant (ISIL, also known as ISIS) targets in Yemen, and recently admitted to having deployed a small number of troops on the ground. The US, along with other western powers such as the United Kingdom and France, has also supplied the Saudi-led coalition with weapons and intelligence.

Iran has denied arming the Houthi rebels, but the US military said it intercepted arms shipments from Iran to Yemen this March, claiming it was the third time in two months that this had occurred. Iranian officials have also suggested they may send military advisers to support the Houthis.

Events in Yemen are viewed as part of Saudi Arabia's "cold war" with Iran.

Saudi Arabia shares a long, porous border with Yemen, and it fears what it sees as Iranian expansionism through its support for Shia armed groups. Commentators in the Arab Gulf states often claim that Iran now controls four Arab capitals: Baghdad, Damascus, Beirut and Sanaa.

In Syria, Saudi-backed rebels are fighting against Bashar al-Assad's government, which is supported by Iran. Lebanon is another arena of conflict: Iran sponsors Hezbollah, the Shia militia and political movement, while Saudi Arabia supports the predominantly Sunni Future Movement.

Tensions between Saudi Arabia and Iran were ratcheted up even further earlier this year, when Saudi Arabia executed Shia Muslim leader Nimr al-Nimr and Iranian protesters attacked the Saudi embassy in Tehran.

Yemen's war is far more complex than a Saudi-Iranian, Sunni-Shia conflict.

Yemen was ruled for a millennium by Zaydi Shia imams until 1962, and the Houthis were founded as a Zaydi Shia revivalist movement. However, the Houthis have not called for restoring the imamate in Yemen, and religious grievances have not been a major factor in the war. Rather, the Houthis' demands have been primarily economic and political in nature.

In 2013, Yemen's National Dialogue Conference was launched, and was tasked with writing a new constitution and creating a federal political system. But the Houthis withdrew from the process because it left Yemen's transitional government in place. Further inflaming matters was the fact that two Houthi representatives were assassinated during the conference's proceedings.

The government's decision to lift fuel subsidies in July 2014 angered the Yemeni public and sparked massive street protests by Houthi supporters and others, who demanded that the government step down. The Houthis proceeded to take over Sanaa in September, forcing the government to flee.

The Houthis were assisted in their advance by former Yemeni President Ali Abdullah Saleh, who was overthrown by protests in 2011, and his supporters.

Al-Qaeda and ISIL have spread as a result of the chaos.

Yemen has long been home to an al-Qaeda franchise, regarded as one of the most dangerous branches of the organisation. Yet the armed group was able to expand its footprint in Yemen amid the chaos following the ousting of Saleh in 2011, taking control of territory in southern Yemen.

Since the start of the war last year, al-Qaeda has launched several attacks on Houthi rebels, whom it views as infidels. In 2015, al-Qaeda took over Mukalla, a provincial capital and the fifth-largest city in Yemen. However, in April 2016, 2,000 Yemeni and Emirati troops launched a ground raid on Mukalla and drove al-Qaeda from the city.

ISIL announced the formation of a wilaya, or state, in Yemen in December 2014. In March 2015, it claimed its first attack in Yemen: suicide bombings in two Sanaa mosques used by Zaydi Shia Muslims, which killed more than 140 people.

Providing aid to civilians in Yemen is very difficult.

Across Yemen, aid organisations are facing major obstacles to helping Yemenis in need of food, medicine, and other essentials. The Houthi siege of parts of the city of Taiz has prevented critical medical supplies from arriving.

Saudi Arabia has pressured aid groups to leave rebel-controlled areas of Yemen, saying that aid workers are at risk. In January 2016, a hospital operated by Doctors Without Borders was hit by a rocket, killing four people. A bombing carried out by the Saudi-led coalition injured at least six people at a hospital run by Doctors Without Borders in October 2015.</s>DUBAI (Reuters) - Amnesty International on Friday denounced Western arms sales to Saudi Arabia and its allies in a coalition battling the Houthis in Yemen, saying such traffic made a "mockery" of a global arms trade treaty.

The rights group accused both the Saudi-led coalition forces and the Iran-allied Houthis of committing potential war crimes in the three-year conflict.

 More than 10,000 people have been killed in Yemen since March 2015 when Saudi Arabia and other Sunni Muslim Arab states launched a military campaign against the Houthis, a group of Shi'ite fighters who had seized the capital and forced President Abd Rabbu Mansour al-Hadi to flee.

 "There is extensive evidence that irresponsible arms flows to the Saudi Arabia-led coalition have resulted in enormous harm to Yemeni civilians," Lynn Maalouf, Director of Research for the Middle East at Amnesty International, said in a statement. 

 "But this has not deterred the USA, the UK and other states, including France, Spain and Italy, from continuing transfers of billions of dollars' worth of such arms. As well as devastating civilian lives, this makes a mockery of the global Arms Trade Treaty."

 The organization said it had documented 36 coalition air strikes since 2015 that appeared to have violated international law, adding that some may amount to war crimes. The documented attacks had killed 513 civilians, including at least 157 children, and wounded 379 others, according to Amnesty. 

 It said the Houthis and their allies had conducted arbitrary arrests and detentions of opponents, and that scores of men and women had been subjected to enforced disappearances and harsh sentences following unfair trails.

 Saudi Arabia and its allies have repeatedly denied allegations of war crimes and say their campaign is directed against Houthi fighters, and not civilians. The Houthi movement has also denied accusations of war crimes.

 Amnesty said that as the conflict enters its fourth year it shows no real signs of abating and that all sides were impeding the delivery of humanitarian aid to at least 22.2 million people in need of assistance and more than one million suffering from suspected cases of cholera.

 The rights group said that despite the loosening of a blockade on Yemeni ports imposed by the Saudi-led coalition, it continues to impose restrictions on aid and commercial imports of essential goods.

 Two rights groups in France said on Friday they would take legal action against the French government unless it halts sales of weapons to Saudi Arabia and its ally the United Arab Emirates within two months.

 Saudi Arabia's Crown Prince Mohammed bin Salman discussed the Yemen conflict with President Donald Trump this week during a visit to the United States.

 U.S. Defence Secretary Jim Mattis told Prince Mohammed on Thursday that there was an urgent need to end the war.

 

 (Reporting By Aziz El Yaakoubi; Editing by Ghaida Ghantous and Peter Graff)</s>Alwaght-Leader of Yemen's Ansarullah movement Abdul Malik Badreddin al-Houthi has stressed that Saudi Arabia will eventually face defeat in its all-out military aggression against the country just as it failed in Syria and Yemen.

Speaking in an exclusive interview with Lebanon’s Arabic-language al-Akhbar daily newspaper published on Friday, Houthi said Saudi Arabia's policies in Yemen are doomed to failure, stressing that the Riyadh regime has not shied away from killing thousands of women and children, targeting crowded markets and social events such as weddings and bombing densely populated neighborhoods, schools and mosques in order to realize its goal of occupying the entire Yemeni soil.

He added that the Yemeni media outlets have sought to expose the extent of the tragedy and horror that the Saudi-led military aggression haunts Yemen and its nation.

The Ansarullah leader went on to say that the unjust economic blockade against Yemen is also aimed at limiting the movement of ordinary people, including patients who are in need of medical treatment abroad, restricting humanitarian supplies, devaluation of local currency, drying up the salaries of civil servants, starving the Yemeni people and destroying factories plus service facilities.

“The Yemeni people have however remained steadfast, and managed to confront all forms of aggression much to the surprise of Saudi-led forces, which though the Yemeni people would surrender within weeks after the military campaign,” he pointed out.

Al-Houthi said, “Saudi Arabia is now in the midst of unprecedented attrition as its political, economic, security and military problems continue to exacerbate.

The Ansarullah chief said Saudi Arabia is being used "like a milking cow" by Americans, emphasizing that US President Donald Trump has been more successful than his predecessor Barack Obama to get money out of the Riyadh regime.

Elsewhere in his remarks, Al-Houthi pointed to Yemen’s missile capabilities, underlining that the main goal is to reach the level of deterrence.

“Our missiles can now reach the heart of enemy areas. They have reached Riyadh and Abu Dhabi. Above all, they have penetrated the US-made air defense systems which they heavily depend on. Our Burkan-2 (Volcano-2) ballistic missiles have reached al-Yamamah Palace in Riyadh and go even longer,” he commented.

Al-Houthi said Yemen's resigned president, Abd Rabbuh Mansur Hadi, and a number of his administration members are currently being incarcerated inside Saudi Arabia.

About 14,000 people have been killed since the onset of Saudi Arabia’s military campaign against Yemen in March 2015. Much of the Arabian Peninsula country's infrastructure, including hospitals, schools and factories, has been reduced to rubble due to the war.

The United Nations says a record 22.2 million people are in need of food aid, including 8.4 million threatened by severe hunger.

In other remarks, al-Houthi Houthi rebels has warned that his fighters would unite with Hezbollah against Israel if a war erupted in Lebanon or Palestine.

He added that "our announcement that we are prepared to send fighters in any Israeli war against Lebanon or Palestine, is based on our principles".

The Ansarullah leader point out that the Israeli regime is "a true enemy" for every Arab and Muslim country, and if Yemen had borders with Lebanon or Palestine, the Ansarullah movement would participate in fighting with the Lebanese and Palestinians.

"We will not be reluctant to send fighters in a new war. Many of Yemen's tribesmen are ambitious to fight against Israel, and they are looking for the day to participate along with the freemen of the Islamic nation against the Israeli enemy," he added.

He said they had informed Hezbollah's leader Sayyed Hassan Nasrallah of their intent to fight. The Ansarullah leader revealed that they had intercepted Israeli regime's military activities in the Red Sea and Mandeb Strait, and added that there had been some Israeli air strikes on the Yemeni coast.

Al Houthi also revealed that the Israeli regime had participated alongside UAE officers in planning several military activities in Yemen.</s>“This proposed sale will support U.S. foreign policy and national security objectives by helping to improve the security of a friendly country which has been, and continues to be, an important force for political stability and economic growth in the Middle East,” the statement said.

“Saudi Arabia will have no difficulty absorbing this equipment and support into its armed forces.”

Hours earlier, Prince Mohammed met with Defense Secretary Jim Mattis, who characterized Saudi Arabia as “part of the solution” in Yemen, which has been ripped apart by civil war.

Before the start of the meeting, a reporter asked Mr. Mattis whether he planned to raise concerns with Prince Mohammed about civilian casualties. Mr. Mattis said the United States was working with other countries to pursue a political solution in Yemen.

He said Saudi Arabia has supported the government in Yemen’s capital, Sana, which is recognized by the United Nations. “We are going to end this war. That is the bottom line,” Mr. Mattis said. “And we are going to end it on positive terms for the people of Yemen but also security for the nations in the peninsula.”

The strife in Yemen, one of the poorest countries in the Middle East, began in 2014, when Houthis, Shiite rebels aligned with Iran, invaded Sana. Those rebels later ousted the government of President Abdu Rabbu Mansour Hadi, a staunch ally of the United States, who was once praised by American officials as a leading partner in the fight against terrorism.

Saudi Arabia, Yemen’s neighbor and a major regional power, began a concerted bombing campaign in early 2015 to help push back the Houthis. But that campaign has long raised the ire of human rights organizations for repeated bombings on civilians, something the Pentagon has admitted it has little oversight of.

One of the last acts of the Obama administration, in December 2016, was to block a transfer of precision munitions to Saudi Arabia because of concerns about civilian casualties that American officials attributed to poor targeting.

That decision blocked the sale by Raytheon of about 16,000 guided munitions kits, which upgrade so-called dumb bombs to smart bombs. It was roundly excoriated by Raytheon and Saudi royal officials.

Since taking office, President Trump has developed a far friendlier relationship with the royal family, and the crown prince in particular, than President Barack Obama had.

A Pentagon spokeswoman, Dana White, said Mr. Mattis did not bring up the mounting civilian casualties in Yemen during his discussion with Prince Mohammed. Instead, she said, the defense secretary discussed the continued cooperation between the United States and Saudi Arabia through additional training and military education.

“Clearly,” said Sarah Margon, the Washington director of Human Rights Watch, “the Trump administration has failed to understand — or simply doesn’t care about — the gravity of the human rights and humanitarian catastrophe in Yemen. Instead of using their leverage smartly to push the visiting Saudi crown prince to stop abuse, the White House is signaling support for large-scale abuse — by unconditionally backing Riyadh with millions more in weapons sales.”

Ms. Margon called on the Senate to “step up to the plate and make clear U.S. support will not go unchecked this time around.”</s>At least seven civilians have been killed when Saudi military aircraft carried out separate airstrikes against residential areas in Yemen’s western coastal provinces of Hudaydah and the northwestern province of Sa’ada as the Riyadh regime presses ahead with its atrocious bombardment campaign against its southern neighbor.

Saudi fighter jets conducted four aerial assaults against a farm in Husseiniyah area of the Bayt al-Faqih district of Hudaydah Province, located 150 kilometers southwest of the capital Sana'a, on Saturday afternoon, leaving five people dead, unnamed local sources told Yemen’s Arabic-language al-Masirah television network.

The sources added that there were children among the deceased.

Meanwhile, two civilians lost their lives and as many sustained injuries when Saudi warplanes targeted their vehicle along a road in the Razih district of Sa’ada Province.

11 killed as Houthis, Hadi loyalists clash in southwestern Yemen

Nearly a dozen people have been killed in overnight clashes between fighters from the Yemeni Houthi Ansarullah movement and militiamen loyal to resigned president Abd Rabbuh Mansur Hadi in the country’s southwestern province of al-Bayda, military and medical officials say.

The officials, speaking on condition of anonymity, said on Saturday that skirmishes in the al-Malagim district of the province have claimed the lives of eight Ansarullah fighters and three Saudi-backed militiamen.

Separately, Yemeni soldiers, backed by fighters from Popular Committees, have struck the positions of Saudi mercenaries in the al-Maslub district of the northern province of al-Jawf, leaving scores of them killed and injured.

About 14,000 people have been killed since the onset of Saudi Arabia’s military campaign against Yemen in March 2015. Much of the Arabian Peninsula country's infrastructure, including hospitals, schools and factories, has been reduced to rubble due to the war.

The United Nations says a record 22.2 million people are in need of food aid, including 8.4 million threatened by severe hunger.

A high-ranking UN aid official recently warned against the “catastrophic” living conditions in Yemen, stating that there is a growing risk of famine and cholera there.

“After three years of conflict, conditions in Yemen are catastrophic,” John Ging, UN director of aid operations, told the UN Security Council on February 27.

He added, “People's lives have continued unraveling. Conflict has escalated since November driving an estimated 100,000 people from their homes.”

Ging said cholera had infected 1.1 million people in Yemen since last April, and a new outbreak of diphtheria has occurred in the war-ravaged Arab country since 1982.</s>Yemen’s Shiite rebels fired a barrage of ballistic missiles targeting Saudi Arabia late Sunday on the third anniversary of a kingdom-led war in Yemen, with fragments of one missile over Riyadh killing one person and wounding two.

The casualties were the first in Saudi Arabia’s capital since the Saudi-led war in Yemen began in March 2015, though previous rockets fired by the Yemeni rebels have caused deaths in other parts of the kingdom.

The rebels known as Houthis said they launched a missile attack targeting Riyadh’s King Khalid International Airport and other sites, again showing their ability to strike deep into the neighbouring kingdom amid the stalemated war in Yemen, the Arab world’s poorest country.

The barrage likely will spark new criticism of Iran’s role in the conflict as well, as the Houthis identified some of the missiles fired as a type that the United Nations and the West say comes from Tehran.

The Saudi military said it intercepted seven ballistic missiles fired by the Houthis at the kingdom, three of them targeting Riyadh, two targeting Jazan and one apiece targeting Najran and Khamis Mushait.

The Saudi-owned satellite news channel Al Arabiya aired footage that it said showed Patriot missile batteries firing at the incoming Houthi missiles. Online videos showed what appeared to be a missile fuselage lying on a street in Riyadh.

One Egyptian national was killed and two other Egyptians suffered wounds when a fragment of a missile over Riyadh fell on a residential neighbourhood, the state-run Saudi Press Agency said.

Houthi ballistic missiles have increased in range over time, with the first one targeting Riyadh fired on May 19, 2017, according to the United Nations. A Nov. 4 launch previously targeted King Khalid International Airport, showing the missiles had a range of over 1,000 kilometres.

The Nov. 4 attack saw the Saudi-led coalition escalate its attacks. It wasn’t immediately clear how the coalition would react to Sunday’s attack, though the barrage marks some 90 Houthi ballistic missile launches targeting Saudi Arabia.

Al Masirah, a Houthi-run satellite news channel, identified some of the missiles fired as the Burkan, or Volcano, missile. The United Nations, Western countries and the Saudi-led military coalition fighting in Yemen all say the Burkan mirrors characteristics of an Iranian Qiam ballistic missile. They say that suggests Tehran either shared the technology or smuggled disassembled missiles to the Houthis who then rebuilt them.

Iran long has denied supplying arms to the Houthis, though a growing body of evidence contradicts their claim.

Meanwhile, the U.S. provides logistical support and weaponry to the Saudi-led coalition, which has been criticized for its airstrikes on Yemen killing civilians, as well as a blockade of Yemeni ports that has brought the country to the edge of famine.

Over 10,000 people have been killed in the conflict, which began after the Houthis and their allies seized Yemen’s capital, Sanaa, in September 2014 and began a march south.</s>Saudi Arabian authorities say one person has been killed and two other wounded in a ballistic missile attack on the kingdom’s capital by Yemeni Shiite rebels known as Houthis.

The death was reported early Monday by the state-run Saudi Press Agency.

Saudi Arabia’s military said seven missiles were fired late Sunday.

Seven ballistic missiles were fired from Yemen, all of them were intercepted, but one intercepter failed and the missile fell in the area.

The missile attack came on the third anniversary of the start of the Saudi-led war in Yemen.</s>Saudi Arabian authorities say one person has been killed and two other wounded in a ballistic missile attack on the kingdom’s capital by Yemeni Shiite rebels known as Houthis.

The death was reported early Monday by the state-run Saudi Press Agency.

Saudi Arabia’s military said seven missiles were fired late Sunday.

Seven ballistic missiles were fired from Yemen, all of them were intercepted, but one intercepter failed and the missile fell in the area.</s>Saudi Arabia claims to have shot down seven ballistic missiles fired by Yemen's Houthi militia, with debris killing a man in what was the first death in the capital Riyadh during the Saudi-led coalition's three-year military campaign in Yemen.

Saudi forces destroyed three missiles over north-eastern Riyadh shortly before midnight, as well as others fired at the southern cities of Najran, Jizan and Khamis Mushait, the coalition said in a statement carried by state news agency SPA.

SPA said one man died and two other people were injured by "falling debris" in Riyadh.

However, videos shared online appeared to show a Saudi defence missile veering off course and crashing into a residential neighbourhood.

Reuters reporters in Riyadh heard several booms and saw smoke in the air.

Another witness said he saw a long stream of light followed by additional explosions.

In the al-Malqa neighbourhood, emergency personnel gathered near a crater in the ground and inspected shattered glass in nearby homes.

Iran' s state-owned Press TV claimed that a missile fired by Houthi rebels in Yemen had targeted King Khalid International Airport in Riyadh but was intercepted.

It also claimed airports in Abha, Najran and Jizan were also targeted by missiles fired from Yemen.

The casualties were the first in Saudi Arabia's capital since the Saudi-led war in Yemen began in March 2015, although previous rockets fired by the Yemeni rebels caused deaths in other parts of the kingdom.

The attacks marked the third time in five months that missiles have flown over Riyadh, as the Houthis step up efforts to demonstrate they can reach the Saudi capital.

The missile attacks threaten to escalate a regional rivalry between Iran and Saudi Arabia.

Houthi ballistic missiles have increased in range over time, with the first one targeting Riyadh fired in May last year, according to the United Nations.

The Saudi-led coalition of Gulf Arab states launched military operations against the Houthis in Yemen in March 2015, after the Iran-aligned Shiite militia seized the Yemeni capital Sanaa and forced President Abd Rabbu Mansour al-Hadi to flee.

Riyadh saw the move as a regional power grab by arch-foe Iran, although the Houthis deny any help from Tehran.

Saudi Arabia has called Iran's alleged supply of rockets to the Houthis "direct military aggression."

The United States, which provides support to the coalition, has also displayed what it said were Iranian-made weapons supplied to the Houthis, calling them conclusive evidence that Tehran was violating UN resolutions.

The conflict in Yemen has killed more than 10,000 people and displaced more than 2 million, unleashing a humanitarian crisis in the Arabian Peninsula's poorest country where nearly 1 million people have been infected with cholera.</s>One person was killed and two others injured in a ballistic missile attack launched from Yemen over Riyadh in Saudi Arabia by Houthi rebels, Saudi civil defence said. The spokesman of Riyadh civil defence said in a statement, “A missile’s shrapnel fell on a residential house in Riyadh, which led to the death of one person and injury of two others. They are all from Egypt.” Saudi Arabian state television said that the Houthis fired two missiles toward the country late Sunday and the Saudi air defence forces succeeded in intercepting one over Riyadh, and another over Jazan in the Saudi Arabian border with Yemen, Xinhua reported.

Citizens in Riyadh said that loud explosions were heard. This is not the first time that Houthis have fired missiles towards Saudi Arabia. In November last year, the Saudi air defence shot down a ballistic missile fired by Houthis at Riyadh International airport. In December, the Houthis fired a ballistic missile toward the Saudi royal palace in Riyadh. Continued missile attacks from Houthi rebels in Yemen have forced Saudi Arabia to cut off air, sea and land links from its neighbour. Saudi defence forces have also halted Yemen’s financial aids and food and fuel imports as well.

Former Yemeni president Ali Abdullah Saleh was killed in Sanaa after days of intense fighting between Houthi rebels and his loyalist forces on December 4. Before killing Saleh, Houthi rebels had reportedly blown up his residence. Both Saleh forces and the Houthi rebels, the latter who is backed by Iran are battling to capture the capital city. The loyalists of Saleh last week had proposed for the talks with the Saudi-led coalition fighting the Houthis to end the three-year conflict in Yemen.

The conflict in Yemen, which began in 2014, has claimed more than 100,000 lives so far. Saleh was overthrown in the ensuing conflict and had reportedly fled to Saudi Arabia for a while. The fighting further intensified in 2015, when clashes broke out between Yemeni President Abdrabbuh Mansur Hadi’s government forces and Saleh loyalist forces.

The Saudi-led coalition forces, which is backed by the United States, has interfered in the conflict upon Hadi’s request since then, and are carrying out regular airstrikes against the Houthi rebels.
Saudi aircraft attack Houthi targets in residential areas of Hudaydah and Sa'dah, Yemen, killing at least seven civilians.
