KIEV, May 15 - The Ukrainian army said Thursday it destroyed two bases of pro-Russian militants in overnight operations after the start of European-brokered talks that have faltered because the two sides will not meet.

President Oleksandr Turchynov told the parliament in the capital of Kiev that government forces attacked a militant base in Slovyansk and another in nearby Kramatorsk in eastern Ukraine. Ukraine's Defense Ministry said there were no casualties.
