Ukraine's air force says Russia launched more than 100 Shahed and decoy drones at Ukraine in nighttime attacks.

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

President Vladimir Putin said, according to a translation by the BBC: "We are determined to have serious negotiations with Ukraine. The purpose is to eliminate the root causes of the conflict and establish long-term, lasting peace with a historical perspective.
