Russian President Vladimir Putin declared an "Easter truce" in the war in Ukraine on Saturday, saying that the Russian side will cease military action from 6 p.m. local Saturday night until midnight April 21.

Putin said he assumes that "the Ukrainian side will follow our example," according to a statement on the Kremlin's Telegram channel. But he also says Russia will respond to "violations of the truce and provocations" by Ukraine, the statement said.

There has been no response yet from Ukrainian President Volodymyr Zelenskyy or Ukrainian officials.
