text: Fresh clashes have broken out in the South Sudanese capital Juba, and at least 66 soldiers have been killed, a day after President Salva Kiir said security forces had put down an attempted coup by supporters of his former deputy. 
   
   The US embassy said on its Twitter account late on Tuesday that that all of its citizens in the country should "depart immediately". The account tweeted that it would outline evacuation options on Wednesday morning. 
   
   "So far we have lost seven soldiers who died while they were waiting for medical attention and a further 59 who were killed outside," doctor Ajak Bullen said on the local Radio Miraya. 
   
   Poor communications in Juba, where the mobile phone system has not operated since Monday evening, meant it was difficult to obtain a broad picture of the number of dead during the clashes, which have involved heavy arms and artillery. 
   
   
   
   Kiir said on Monday the fighting between army factions was a bid to seize power by the former vice president, Riek Machar, whom he sacked in July. 
   
   The two men, from different ethnic groups, which have clashed in the past, have long been political rivals. Analysts said divisions between them run deep and rivalries in army ranks have long simmmered. 
   
   Al Jazeera's Rawya Rageh, reporting from neighbouring Nairobi, spoke to South Sudan's Information Minister Michael Makuei Lueth who confirmed at least 10 very senior former government officials have been arrested, including six cabinet ministers. The government named the men on its website. 
   
   There are conflicting reports about the whereabouts of Riek Machar. The government claims he is on his way to Unity State, whereas Machar's spokesperson said he is in fine condition and "very much still in Juba", Rageh said. 
   
   Heavy weapons 
   
   Gunfire - including the sporadic firing of heavy weapons - resumed in the early hours of Tuesday and was still audible at 9am (0600 GMT). It appeared to come from a military headquarters, a few kilometres from the centre of town. 
   
   Residents near Juba airport, which has been closed since Monday, were woken before dawn by gunshots and blasts, a UN worker said. Others also reported bouts of shooting. 
   
   The streets of Juba were deserted, with only military vehicles to be seen and civilians barricaded in their homes. 
   
   Kiir had said in a statement on Monday that security forces had regained control, although a dawn-to-dusk curfew had been imposed. 
   
   "The attackers went and [the] armed forces are pursuing them," Kiir said. "I promise you today that justice will prevail." 
   
   Details of the claimed coup remained sketchy, but South Sudan's Foreign Minister Barnaba Marial Benjamin told the Associated Press news agency that troops in the main army base raided a weapons store in Juba but were repulsed. 
   
   Civilians take refuge 
   
   The UN deputy special representative for South Sudan, Toby Lanzer, told Al Jazeera on Tuesday that about 16,000 civilians were now taking refuge from the fighting in two UN compounds. 
   
   "We will of course do everything we can do protect people. Many people who are coming require health care of all types," he said. 
   
   "Some people have been injured. We've got challenges of a variety - and the water and sanitation situation is also something that we are grappling with." 
   
   Tension had been mounting in South Sudan since Kiir's sacking of Machar. The men belong to different ethnic groups - Kiir to the Dinka, the most powerful, and Machar to the Nuer, but it is not clear whether this latest tension is due to ethnic or political divisions. 
   
   Machar, who has expressed a willingness to contest the presidency in 2015, told Al Jazeera in July that if the country is to be united it cannot tolerate "one man's rule or it cannot tolerate dictatorship." 
   
   His sacking, part of a wider dismissal of the entire cabinet by Kiir, had followed reports of a power struggle within the ruling party. 
   
   South Sudan's government has struggled to create a functioning state since it declared independence from Sudan in 2011 after years conflict with Khartoum during a war that often saw south-south clashes. ||||| Story highlights "It's dozens and dozens, scores of casualties," the head of the U.N. Security Council says 
   
   About 15,000 to 20,000 civilians have fled to United Nations bases in the city, he says 
   
   State Department says U.S. Embassy suspending normal operations until further notice 
   
   Sporadic gunfire still rattling Juba, diplomats say 
   
   The death toll from violence in South Sudan is "heavy," the United Nations said Tuesday, and thousands of people have sought refuge in the organization's compounds in Juba. 
   
   Gunfire rang out again in the capital of in Africa's newest nation just hours after the country's President said his forces had halted a coup attempt. 
   
   Clashes, which began on Sunday evening, have left hundreds in urgent need of medical care, the International Committee of the Red Cross (ICRC) said. 
   
   Gerard Araud, the French representative to the United Nations and the current President of the Security Council, said precise figures on the death toll weren't available. 
   
   "But it's heavy," he said. "It's dozens and dozens, scores of casualties, it's really not a minor incident." 
   
   Officials at the United Nations are "extremely concerned" about the violence, Araud said, due to the high number of casualties and because the fighting appears to be between different ethnic groups in South Sudan. 
   
   On Tuesday, sporadic gunshots were heard in the area of Tonping, the U.S. Embassy said on its Twitter feed, quoting U.N. radio. It recommended that U.S. citizens currently in the country depart immediately. 
   
   Women and children carrying bags, kettles, pots and basic belongings arriving at a U.N compound to seek shelter could be seen in pictures posted on the U.N. mission in South Sudan (UNMISS) Facebook page. 
   
   Araud said Tuesday evening that around 15,000 to 20,000 civilians were taking refuge in the two UNMISS compounds in Juba, putting a strain on supplies of medicine, food, water and security resources. 
   
   In a televised address Monday, South Sudan President Salva Kiir blamed soldiers loyal to his sacked deputy Riek Machar for starting the fighting Sunday evening. 
   
   Dressed in fatigues, he said the government was in full control of the capital and announced a nighttime curfew. 
   
   Ten people were arrested in connection with the foiled coup, according to a statement posted Tuesday on the South Sudan government website. 
   
   Hundreds in need of medical care 
   
   The ICRC said it was providing Juba's two major hospitals with support, such as wound-dressing materials, to cope with the heavy influx of patients. 
   
   More than 300 people have been admitted to Juba Teaching Hospital and Juba Military Hospital over the past two days, it said. 
   
   "We know there are more people who need care, but they are having difficulty reaching healthcare facilities because of the security situation and the lack of available transportation," Felicity Gapes, an ICRC delegate leading the medical response on the ground, said in a statement. 
   
   "Staff in both hospitals have been working around the clock, but they are struggling because of the sheer volume of patients and the severity of the injuries." 
   
   The United Nations said Secretary-General Ban Ki-moon spoke with Kiir by phone Tuesday, expressing his concern about the fighting. 
   
   He urged "all parties to cease hostilities immediately, and called on the government to exercise restraint in the management of the situation and to guarantee the protection of all civilians regardless of their ethnicities." 
   
   Deep-running tensions 
   
   Kiir's dismissal of his Cabinet in July further inflamed deep tensions between his Dinka community and Machar's Nuer community. 
   
   South Sudan formally split from Sudan in 2011 following a referendum, after decades of conflict. Numerous armed groups remain active in the oil-rich country. 
   
   UNMISS said Hilde F. Johnson, special representative of the U.N. secretary-general, called on "all parties in the current situation to refrain from any community-motivated violence." 
   
   "At a time when unity among South Sudanese is more needed than ever, I call on the leaders of this new country and all political factions and parties, as well as community leaders to refrain from any action that fuels ethnic tensions and exacerbates violence," Johnson said. 
   
   Juba's international airport remained closed. And with phone networks sketchy, embassies were turning to social media to stay in touch with their citizens, mainly calling on them to stay home and avoid unnecessary movement. 
   
   The State Department said U.S. citizens currently in South Sudan should leave immediately, and it ordered the departure of non-emergency U.S. government personnel from the country. 
   
   "The Embassy is also suspending normal operations until further notice and cannot provide routine consular services to U.S. citizens in South Sudan," it said. 
   
   The African Union said it was "deeply concerned" about the events in South Sudan, urging the government, leadership and other stakeholders to exercise maximum restraint and avert any further escalation. ||||| The U.S. Department of State warns U.S. citizens against all travel to the Republic of South Sudan and recommends that U.S. citizens currently in South Sudan depart immediately.

target: – The State Department today issued a travel warning for South Sudan, recommending that all Americans "depart immediately," as violence rises in the wake of an attempted coup. That includes non-emergency US personnel, who have already been ordered to depart, forcing the US to suspend normal operations at its embassy there until further notice. At least 66 soldiers have been killed so far in clashes in Juba, the capital of the world's newest country, al-Jazeera reports. Gunshots rang out within earshot of the embassy, and military vehicles roamed the mostly empty streets as residents barricaded themselves inside. The UN says that roughly 10,000 people have sought refuge at the two UN compounds there, according to CNN, and hospitals are straining to deal with an influx of patients.
