The Ukrainian and Russian Defence ministries have agreed on a truce in Crimea until March 21, Ukraine's acting defence minister said Sunday.

"An agreement has been reached with (Russia's) Black Sea Fleet and the Russian Defence Ministry on a truce in Crimea until March 21," Ihor Tenyukh told journalists on the sidelines of a cabinet meeting. "No measures will be taken against our military facilities in Crimea during that time. Our military sites are therefore proceeding with a replenishment of reserves."

Crimeans voted in a referendum Sunday on whether to break away from Ukraine and join Russia, with Kiev accusing Moscow of rapidly building up its armed forces on the peninsula in "crude violation" of an international treaty.
