Four Ukrainian soldiers killed as fighting tests truce

KIEV (Reuters) - Four Ukrainian servicemen have been killed and 14 wounded in fighting with pro-Russian rebels in the past 24 hours, the Ukrainian military said on Thursday, as a new wave of violence rekindled concerns a ceasefire deal could be crumbling.

A notable increase in military and civilian casualties in the past two weeks has prompted the leaders of France and Germany, who helped broker the six-month-old truce, to arrange new talks with President Petro Poroshenko to discuss how to preserve the peace.
