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 3-year war.

Ukraine's air force reported an overnight Russian attack involving more than 100 drones, as Russia's President Vladimir Putin rejected Ukrainian President Volodymyr Zelensky 's proposal of an immediate 30-day ceasefire.

Major European powers threw their weight behind an unconditional 30-day Ukraine ceasefire on Saturday, with the backing of U.S. President Donald Trump, and threatened President Vladimir Putin with "massive" new sanctions if he did not accept within days.
