Ukraine and pro-Russian separatists, in a gesture to shore up a tenuous ceasefire, agreed on Wednesday to strive for an end to all truce violations from next Tuesday, the OSCE and rebel representatives said.

U.S. Defense Secretary Ash Carter and the nation's spy chief this week urged a key Senate committee to amend federal law to allow a joint venture of the two largest U.S. arms makers to use more Russian RD-180 rocket engines.

A fragile ceasefire between Ukrainian government forces and pro-Russian separatists came under renewed pressure on Sunday with the Ukrainian military reporting a serviceman had been killed and seven others wounded in rebel attacks.
