Drone and missile attacks also leave dozens injured on eve of crucial vote on anti-corruption bodies

• Russia–Ukraine war – latest updates

Russian strikes on Kyiv overnight have killed at least six people, including a six-year-old boy, according to local officials, with drones and missiles hitting at least 27 sites and leaving a further 30 people hospitalised, including nine children. A nine-storey residential building partly collapsed after it was struck.

Explosions rang out for hours, making it another sleepless night for many in the Ukrainian capital before a crucial parliamentary vote on Thursday on legislation to restore independence to two anti-corruption bodies. The bill, if passed, would essentially undo a law passed last week that curtailed their powers and led to a political crisis.
