The invasion began on the morning of 24 February, when Putin announced a "special military operation" to "demilitarise and denazify"" Ukraine. Minutes later, missiles and airstrikes hit across Ukraine, including the capital Kyiv. A large ground invasion followed from multiple directions. Ukrainian president Volodymyr Zelenskyy enacted martial law and a general mobilisation of all male Ukrainian citizens between 18 and 60, who were banned from leaving the country. Russian attacks were initially launched on a northern front from Belarus towards Kyiv, a north-eastern front towards Kharkiv, a southern front from Crimea, and a south-eastern front from Luhansk and Donetsk.
