Vladimir Putin has called for a 36-hour ceasefire in Ukraine this weekend to mark the Russian Orthodox Christmas holiday.
The truce in the war, which began almost 11 months ago, would run from noon on January 6 to midnight on January 7, the Kremlin said.
Putin did not appear to make his ceasefire order conditional on a Ukrainian agreement to follow suit, and it was not clear whether hostilities would actually halt on the 1,100-kilometre (684-mile) frontline.
