Ukraine: Donetsk civilians 'in need of aid'
10 August 2014 Last updated at 08:35 BST
Pro-Russian rebels in eastern Ukraine have called for a ceasefire and aid to avoid a "humanitarian catastrophe" in Donetsk.
Ukrainian President Petro Poroshenko has said he is ready to consider allowing humanitarian assistance into the rebel-held area of eastern Ukraine.
However, he said that any mission into Donetsk must be international and unarmed, and could only enter through Ukrainian-controlled checkpoints.
Russia has repeatedly called for humanitarian help for civilians in eastern Ukraine.
