Seven Ukrainian soldiers killed in rebel attack, straining ceasefire

KIEV (Reuters) - Seven Ukrainian soldiers were killed when separatist shelling hit their armoured vehicle near Donetsk airport in eastern Ukraine, a military spokesman said on Monday, putting a fragile ceasefire under further strain.

It was the largest loss of life among Ukrainian soldiers in a single incident since the ceasefire came into force on Sept. 5 and cast a shadow over President Petro Poroshenko's upbeat assertion last week that the worst of the war against the separatists was over.
