A Red Cross aid convoy prepared to enter the shattered Baba Amro district of Homs yesterday after a Syrian official declared the area "cleansed" and the opposition spoke of a massacre by President Bashar al-Assad's forces.

The residential district became a symbol of resistance to Assad after government troops surrounded it with tanks and artillery and shelled it intensively for weeks, killing and wounding civilians cowering in its ruined buildings.

Rebels withdrew on Thursday in a key moment in the year-old uprising. An official at Syria's Ministry of Foreign Affairs and Expatriates said the army had "cleansed Baba Amro from the foreign-backed armed groups of terrorists."

Activists said Syria's army had begun hunting down and killing insurgents who had stayed to cover their

comrades' retreat, although the reports could not be verified. They said 10 young men were shot dead on Friday.

In Geneva, the United Nations human rights body reminded Assad of his obligations under international law. "We are alarmed at reports starting to come out of the Baba Amro district of Homs after it was taken over by government forces yesterday," spokesman Rupert Colville said.

Meanwhile, the two French journalists who were trapped in Homs had been evacuated and headed home on Friday.

A plane transporting reporter Edith Bouvier and photographer William Daniels had left Beirut for Paris, the French embassy in the Lebanese capital said, and was to land around 6:00pm local time at a military airport.

French officials announced late Thursday that Bouvier, 31, and Daniels, 34, had escaped to Lebanon

after being trapped for days under bombardment in the central Syrian cityofHoms.

In Beirut, the International Committee of the Red Cross (ICRC) said Syrian authorities had agreed that the Syrian Arab Red Crescent and the ICRC could enter Baba Amro to evacuate casualties and to take food and medicine to civilians trapped by the fighting and siege.

"We have positive indications from the Syrian authorities to go in. We are ready to enter Baba Amro to evacuate first the sick and wounded and to take food and medical supplies," Samar al-Kadi, ICRC spokeswoman in Beirut, told Reuters.

The ICRC later said a convoy had reached Homs and was preparing to enter Baba Amro. The rebel Free Syrian Army (FSA) said on Thursday it was leaving the district — normally home to 100,000 residents. Only a few thousand people remain.

Conditions in the heavily bombarded district are hellish. TV footage showed heavy snow and freezing weather, with residents lacking electricity or fuel for heating. There is also a shortage of food and medical supplies.

Barely a building has escaped damage from artillery shelling and many are pock-marked with bullet holes.

In a rare show of unity with Western powers, Russia and China joined other Security Council members at the United Nations in expressing "deep disappointment" at Syria's failure to allow the UN humanitarian aid chief Valerie Amos to visit the country, and urged that she be allowed inimmediately.

France announced it would shut its Syrian embassy and was ready to step up support of the rebels if the UN Security Council cleared the way for such a move. British Prime Minister David Cameron said Syria's rulers would be held to account.
