Ukrainian military jets shot down by rebels, says Kiev

Two Ukrainian military fighter jets have been shot down by pro-Russian separatists in the east of the country, according to the defence ministry in Kiev.

The claims have not been confirmed by the rebels themselves - the BBC's Natalia Antelava said she had not heard anything despite being in the same area, but a separatist commander had yesterday said: "Watch the news tomorrow."

If the jets had been shot down, she added, it would mean rebels had broken their promise to allow investigators safe access to the crash site.
