Russia launched a barrage of 108 drones at Ukraine overnight, Kyiv said, in defiance of a proposed 30-day ceasefire starting today. Up to 55 of the drones were shot down, the air force said, adding that a civilian freight train had been hit, injuring its driver.

Ukraine’s Western allies said they would strengthen sanctions if Russia refused an unconditional 30-day ceasefire.

European leaders from Britain, France, Germany and Poland joined Ukrainian President Volodymyr Zelensky in Kyiv in urging Russian President Vladimir Putin to accept a 30-day ceasefire or face more sanctions.
