The United States has called on the Syrian government to allow convoys into Homs, where "people are starving". America added that the evacuation of women and children from the city was "not sufficient."
Meeting Syria's regime and opposition delegates separately has been "very useful" to the peace talks taking place in Geneva, said the UN mediator Lakhdar Brahimi.
The two sides are due to meet again tomorrow morning. "They will be doing most of the talking to one another through me, and most probably in the afternoon I [will] see them seprately again," he added.
Syria's regime and opposition have agreed that women and children can leave the besieged city of Homs, but relations remain fragile.
