Separatist rockets streaked across hills in eastern Ukraine on Monday as rebels pounded the positions of Ukrainian government troops holding a strategic rail town while both sides pressed ahead with mobilizing more forces for combat.

Kiev’s military said five more Ukrainian soldiers were killed in clashes while municipal authorities in the big rebel-controlled city of Donetsk said 15 civilians were killed at the weekend by shelling in a surge of violence following the collapse of a new peace effort on Saturday. MORE
