Ukraine's interim Prime Minister Arseniy Yatsenyuk has accused Russian President Vladimir Putin of trying to "restore the Soviet Union", in an interview on US television.

Speaking on NBC's Meet the Press, Mr Yatsenyuk says that if Mr Putin is successful, it will be "the biggest disaster of this century".

Addressing disputed claims of anti-Semitism by pro-Russian separatists in Donetsk, the prime minister said he had urged Ukraine's security forces to bring the perpetrators to justice.

The full interview airs later on Sunday.
