Russia sent hundreds of drones toward Ukraine overnight into Wednesday, with four key regions coming under heavy attack and President Volodymyr Zelensky’s hometown facing “massive” bombardment, officials said.

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.

A coalition of Ukrainian hackers breached and wiped systems belonging to Gaskar Group, a Moscow-based drone maker.
