A Ukrainian security official said Sunday that attacks by Russia-backed rebel fighters are continuing despite a cease-fire called for by both sides more than two weeks ago.
Col. Andriy Lysenko, a spokesman for Ukraine's national security council, said two Ukrainian servicemen and about 40 rebels had died in clashes over the past day. He said the fighters fired on Ukrainian positions at 22 locations and that they fired artillery at the airport in Donetsk, the largest rebel-held city.
