A convoy of Ukrainian armed forces including armoured personnel carriers, military vehicles and cannons prepare to move as they pull back from the Debaltseve region, in Paraskoviyvka, eastern Ukraine, February 26, 2015. Ukrainian troops towed artillery away from the front line in the east on Thursday, a move that amounted to recognising that a ceasefire meant to take effect on Feb. 15 was holding at last.
