Russia has launched one of its biggest air attacks on Ukraine of the war so far, the head of the Ukrainian air force has said. At least six people were killed and dozens wounded as missiles and drones were fired into more than half of Ukraine's regions on Monday. Power infrastructure was hit, causing widespread blackouts, as the entire country was put under air raid alert and told to take shelter. Russia confirmed it had launched attacks on Ukraine's energy infrastructure - one of its long-term tactics - and said all its targets were hit. According to Mykola Oleshchuk, the commander of Ukraine's air force, Russia launched 127 missiles and 109 attack drones.
