Russia is "completely ignoring" a 30-day ceasefire proposed by Ukraine and European powers that was to have begun on Monday, Ukrainian Foreign Minister Andrii Sybiha said.

The Ukrainian air force says Russia launched more than 100 Shahed and decoy drones at Ukraine in nighttime attacks, after the Kremlin rejected an unconditional 30-day ceasefire in the more than 3-year war.

Russia resumed mass drone attacks in Ukraine early on Sunday, after its self-declared three-day pause expired.
