Ukrainian President Volodymyr Zelenskyy has accused Vladimir Putin of “playing games” after the Russian leader proposed a three-day unilateral ceasefire to coincide with Moscow’s Victory Day commemorations, Aljazeera reported.

“This is more of a theatrical performance on his part. Because in two or three days, it is impossible to develop a plan for the next steps to end the war,” Zelenskyy told a small group of journalists on Friday, in remarks embargoed until Saturday.

Russia announced a 72-hour halt in hostilities beginning May 8, but has so far rejected an unconditional 30-day ceasefire pushed by Ukraine and the United States, which is trying to broker an end to the three-year war.

Zelenskyy said Ukraine would not be “playing games to create a pleasant atmosphere to allow for Putin’s exit from isolation on May 9” when some foreign leaders are due in Moscow for Russia’s World War II commemorations, according to Aljazeera.
