The UN's emergency relief coordinator Valerie Amos has arrived in Syria to discuss ways of getting aid to the estimated two million people caught up in the country's conflict.
Diplomats warn that, unless the violence eases, it will be impossible to get emergency relief to the worst affected areas.
Meanwhile, Syria's PM Riad Hijab has spoken out for the first time since his defection last week, and warned that the regime controls no more than 30% of the territory.
