Boris Johnson accused Vladimir Putin of committing war crimes as he condemned "abhorrent" attacks on the citizens of Ukraine. The UK fears the Russian leader will unleash even greater force against Kyiv and other Ukrainian cities in the coming days.
The Prime Minister spoke to Ukraine's President Volodymyr Zelensky on Wednesday morning, promising further support and weapons for the forces resisting Russia's military. Strikes that damaged the Babi Yar Holocaust memorial in Kyiv and the central square in Kharkiv have caused revulsion, and Western allies fear it is a sign of a shift in Russian tactics towards indiscriminate targeting of urban areas.
At Prime Minister's Questions on Wednesday lunchtime, Mr Johnson said: "Putin has gravely miscalculated; in his abhorrent assault on a sovereign nation, he has underestimated the extraordinary fortitude of the Ukrainian people and the unity and resolve of the free world in standing up to his barbarism."
