Russia launched more than 100 Shahed and decoy drones at Ukraine in nighttime attacks, the Ukrainian air force said Monday, after the Kremlin rejected an unconditional 30-day ceasefire in the more than three-year war. There was no response from the Kremlin, meanwhile, to Ukrainian President Volodymyr Zelenskyy’s challenge for Russia’s President Vladimir Putin to meet him for face-to-face peace talks in Turkey this week. 

The United States and European governments have made a concerted push to stop the fighting, which has killed tens of thousands of soldiers on both sides as well as more than 10,000 Ukrainian civilians. Russia’s invading forces have taken around one-fifth of Ukraine. In a flurry of diplomatic developments over the weekend, Russia shunned the ceasefire proposal tabled by the US and European leaders but offered direct talks with Ukraine on Thursday.
