Russia's invasion of Ukraine is a ‘catastrophe for our continent’, said Boris Johnson. He chaired an emergency Cobra meeting on 24 February and gave a televised statement after Russian forces launched an assault on Ukraine, crossing its borders and bombing military targets near big cities. He outlined new sanctions against Russia in the Commons and said on Twitter that he would also speak to his fellow G7 leaders. He called for an urgent meeting of all NATO leaders as soon as possible. In a phone call with Ukrainian president Volodymyr Zelensky, Mr Johnson vowed the West ‘would not stand by as Putin waged his campaign against the Ukrainian people’ and tweeted earlier, ‘Putin has chosen a path of bloodshed and destruction by launching this unprovoked attack on Ukraine.’ Foreign secretary Liz Truss has demanded that the Russian ambassador explain Russia's ‘illegal, unprovoked invasion of Ukraine’.
