KIEV (Reuters) - At least six Ukrainian servicemen were killed in separatist attacks on Sunday in Ukraine's troubled eastern regions in a grim weekend marking the first anniversary of a rebellion against Kiev's pro-Western rulers.

Four Ukrainian soldiers died when their vehicle was hit by a shell fired by the Russian-backed rebels as it drove across a bridge in the government-held town of Schastye, 170 km (105 miles) north-east of the big regional centre of Donetsk, regional police said.
