Russian President Vladimir Putin announced a temporary Easter ceasefire in Ukraine starting Saturday, citing humanitarian reasons, as Russia and Ukraine swapped hundreds of captured soldiers in the largest exchange since Moscow’s full-scale invasion started over three years ago. According to the Kremlin, the ceasefire will last from 8:20 PM IST on Saturday to midnight following Easter Sunday.

“We assume that the Ukrainian side will follow our example. At the same time, our troops must be ready to repel possible violations of the truce and provocations from the enemy, any of its aggressive actions,” Putin said at a meeting with Chief of the General Staff Valery Gerasimov, in a video shared by the Kremlin’s Press Service.
