The unilateral ceasefire coincides with the celebrations in Moscow for the 80th anniversary of victory over Nazi Germany in World War II, Russia’s biggest secular holiday. Kyiv has pressed for a longer-term cease-fire.

Ukraine has called the Kremlin’s ceasefire a ruse by Russian president Vladimir Putin to create the impression he wants to end the war, which began when Russia invaded its neighbouring country in February 2022. Mr Zelensky said Russia had given no response to the 30-day offer except for new strikes.

Events to mark the holiday in the occupied territories seem to be an effort to show Russian control of land it has captured.
