Sergei Lavrov, the Russian foreign minister, just wrapped up an hour long press conference, confirming that despite an increase in diplomatic activity, Russia's fundamental position on Syria hasn't changed. Lavrov is due to host Kofi Annan tonight. Annan will then meet with Vladimir Putin, the president, tomorrow. Syrian opposition leaders were in Moscow last week. Lavrov reiterated his stance that Russia is not taking sides in the conflict, but that it remains opposed to western intervention there. He lashed out at the west for blaming Russia and said that he saw "elements of blackmail" in threats that the UN observer mission in Syria, which Russia supports, would fail to see its mandate extended later this month if Moscow failed to agree to UN sanctions, which it has criticised. 10.13am: Hundreds of people have fled fierce fighting in the Syrian capital, activists have told Reuters: Heavy clashes broke out between rebels and government forces in the Syrian capital Damascus for the second day running on Monday, forcing hundreds to flee, activists said.

Another activist said violence had also broken out in the city's southern district of Tadamon. Earlier in the morning columns of armoured vehicles were seen on the main road leading to Tadamon. Activists said Sunday's violence was the heaviest fighting in the capital since the start of the 17-month-old revolt against President Bashar al-Assad. 10.05am: Damascus is not the only place where there are clashes between government troops and the rebel Free Syrian Army, according to the Local Coordination Committees activist group.

Welcome to Middle East Live. Intense fighting is reportedly continuing in Damascus. Activists reports fresh fierce clashes between the Free Syrian Army and government troops in Damascus after Sunday saw what residents said were the worst clashes to hit the capital so far. Rebels from the Free Syrian Army seem to be creeping ever closer to the centre of Damascus, the BBC reports. Activists said on Sunday that the Syrian army had closed down the road to the airport and was trying to surround fighters in southern neighbourhoods such as al-Tadamon and Hajar al-Aswad in an attempt to crush unrest inside Damascus. The UN and Arab League envoy, Kofi Annan, will meet the Russian president, Vladimir Putin, and Russia's foreign minister in Moscow today as he seeks to break the diplomatic deadlock on Syria. Western countries are pushing for a chapter 7 UN security council resolution, which could pave the way for the use of force. Russia has said it will not support such a resolution. The International Committee of the Red Cross says Syria is now in a state of civil war. The ICRC is considered to be a guardian of the Geneva conventions, which prescribe the rules of warfare. Therefore it could help lay the ground for war crimes prosecutions. The Syrian government on Sunday denied that it used tanks and helicopters to attack the village of Tremseh in Hama province on Thursday. Activists reported mass killings in the village, but foreign ministry spokesman Jihad Makdissi said only two civilians and 37 armed individuals were killed in what Damascus said was a defensive operation. He denied the army had used tanks, helicopters and heavy weapons to target the town. Egypt's top military official stepped up his feud with the Muslim Brotherhood on Sunday, saying the army would prevent Egypt from falling to a "certain group," the New York Times reports, citing the state news agency. The remarks by the official, Field Marshal Mohamed Hussein Tantawi, did not mention the Brotherhood by name but were widely seen as a reference to the group and to Mohamed Morsi, Egypt's newly elected president and a former Brotherhood leader. And they came just hours after secretary of state Hillary Rodham Clinton met with the field marshal in Cairo in an effort to prod Egypt's military to hand its power to civilians. Egypt's political upheaval will be the focus of discussions when Clinton visits Israel today, Reuters reports. "At the top of it (her agenda) will be her impressions and assessment of the last two days that she spent in Egypt," a senior US official told reporters on condition of anonymity. "She is bringing a very calming message," Danny Ayalon, the Israeli deputy foreign minister, told Israel Radio. By their (the US) reckoning as well, Egypt's agenda, and certainly President Morsi's agenda, will be a domestic agenda. Libya's Olympic committee president was taken from his car by gunmen in Tripoli on Sunday and his whereabouts are unknown, colleagues said. Nabil Elalem was in his car with a colleague when two vehicles carrying men in military-style clothing blocked them off, another colleague, Arafat Jwan, said.
