Ukrainian President Volodymyr Zelenskyy called on Saturday for stronger sanctions on Moscow after a Russian drone killed nine bus passengers in northeastern Ukraine just hours after the two countries held their first peace talks in three years of war.

Ukraine rallied support from its Western allies on Friday after Kyiv and Moscow failed to agree to a ceasefire at their first direct talks in more than three years, with Russia presenting conditions that a Ukrainian source described as "non-starters".
