Trucks from Russia's aid convoy to Ukraine have begun to turn back towards Russia.
President Obama and the German Chancellor accused Moscow of a dangerous escalation of tension in eastern Ukraine, after the aid convoy entered a rebel-held area without approval from Kiev.
The convoy had arrived in the rebel stronghold of Luhansk, where there has been fierce fighting.
