Russian President Vladimir Putin says that the attacks on Ukraine’s energy infrastructure were a response to Kiev’s strikes on Russia’s power lines.

Ukraine claims shooting down scores of incoming Russian missiles.

NATO says it will deliver anti-drone systems to Ukraine in the coming days to help it fend off Russian aerial attacks, including those carried out with unmanned aerial vehicles (UAVs).

Ukrainian President Volodymyr Zelensky says Russian airstrikes have destroyed 30 percent of his country’s energy infrastructure in the past week and have caused “massive blackouts” across Ukraine.
