Ukraine's Poroshenko says Kiev will destroy rebels behind missile attack

KIEV (Reuters) - Ukrainian President Petro Poroshenko said that Kiev would "find and destroy" the pro-Russian separatists responsible for a high-powered missile attack that possibly killed 30 Ukrainian servicemen on Friday. "For every soldier's life, the militants will pay with scores and hundreds of their own. Not a single terrorist will avoid responsibility, each will get what they deserve," he said in a statement on his website following an emergency meeting of security chiefs.
