The International Committee of the Red Cross has sent 35 staff to help smooth the way for a Russian humanitarian convoy, which has arrived at the Ukraine border.
"We are ready to roll with this convoy, there has been a last-minute delay. We are hopeful that it will be resolved shortly," ICRC spokesman Ewan Watson told Reuters.
The first vehicles of the Russian aid convoy were allowed to cross the border between Russia and Ukraine earlier. They are being inspected by Ukrainian officials in a territory beyond the Russian checkpoint.
