Ukraine's acting President has told the country's parliament that "terrorists" armed with anti-aircraft missiles were responsible for shooting down a military helicopter near the town of Slaviansk.
Fourteen servicemen, including a general, reportedly died in the attack in the east of the country.
"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," Oleksandr Turchinov said.
