Russia intensifies air strikes and missile attacks on Ukraine

Russia has increased its night-time aerial attacks over Ukraine ahead of a renewed Ukrainian counteroffensive. Air raid sirens have been heard in Kyiv and across two-thirds of Ukraine, with at least four people killed on Monday. The United Nations has said at least 8,791 civilians have been killed since Russia launched its full-scale invasion of Ukraine in February last year. Russian President Vladimir Putin is due to preside over Victory Day celebrations in Moscow later on Tuesday when he is expected to address thousands of troops standing to attention in Moscow’s Red Square.
