Ukraine President Volodymyr Zelenskyy has reacted sharply to Prime Minister Narendra Modi's brief visit to Russia and his interaction with Russian President Vladimir Putin. In a post on X (formerly Twitter) Mr Zelenskyy referred to Russia's attack Monday - in which at least 37 people, including three children, were killed after a missile strike on a children's hospital in Kyiv. The strike also damaged nearly 100 buildings, including schools and maternity hospitals.
