DEBALTSEVE, Ukraine (Reuters) - Searching through the rubble strewn throughout the eastern Ukrainian town of Debaltseve, a separatist picked out the ammunition left by fleeing government troops before pro-Russian rebels captured the town this week.

"These are ours now, and we'll use them against (the Ukrainians) themselves. We have to expand," said the rebel who refused to give his name, straightening up while a dozen others continued their search for arms and ammunition.
