(Reuters) - Pro-Russian separatists on Thursday shot down a Ukrainian military helicopter in eastern Ukraine and 14 people on board, including a general, were killed, acting President Oleksander Turchinov told parliament.

"I have just received information that terrorists using Russian anti-aircraft missiles shot down our helicopter near Slaviansk. It had been ferrying servicemen for a change of duty," Turchinov said.
