Ukraine's air force said Russia targeted several regions overnight with 267 drones, of which around 200 were Shahed attack drones and the rest decoys. The air force said it shot down or otherwise suppressed 244 drones. Twenty-three drones impacted across seven locations, with falling debris reported in nine locations, the air force said.

US President Donald Trump has announced the US will send "top-of-the-line weapons" to Ukraine via Nato countries, while also threatening Russia with severe tariffs if a deal to end the war is not reached within 50 days.

Trump's moves underline his growing disenchantment with Russian President Vladimir Putin over the lack of progress in U.S.-led efforts to secure a ceasefire.
