Ukraine imposed sanctions on three Chinese companies on Friday claiming they were involved in production of advanced Iskander missiles, a day after President Volodymyr Zelenskiy alleged that China had been supplying weapons to Russia.

Russian President Vladimir Putin declared a brief “Easter truce” in his war with Ukraine, saying “all hostilities” will pause for a two-day period. Russian fighting will halt between 6 p.m. Moscow time on Saturday (11 a.m. ET) and midnight on Monday (5 p.m. Sunday ET), he said.
