Five more Ukrainian soldiers have been killed in fighting with Russian-backed separatists in the past 24 hours, a military spokesman said on Thursday. The fresh casualties were announced as separatists continued attacks on Debaltseve, a key rail hub northeast of the big city of Donetsk which government troops are holding despite strong pressure from the rebels.
