Ukraine's armed forces plan to launch a "full-scale anti-terrorist operation" against pro-Russian separatists, acting president Oleksander Turchinov said on Sunday, raising the risk of a military confrontation with Moscow.

Angered by the death of a state security officer and the wounding of two of his comrades near the flashpoint eastern city of Slaviansk, Turchinov gave rebels occupying state buildings until Monday morning to lay down their weapons.

He blamed Russia, which opposed a pro-Europe uprising that forced Moscow-backed former president Viktor Yanukovich to flee, for being behind the rash of rebellions across Russian-speaking towns in eastern Ukraine.

"The blood of Ukrainian heroes has been shed in a war which the Russian Federation is waging against Ukraine," he said in an address to the nation. "The aggressor has not stopped and is continuing to sow disorder in the east of the country."
