Volodymyr Zelenskyy says at least 14 people have died,
including six children, following a Russian missile strike on the Ukrainian president's hometown of Kryvyi Rih.
He said rescue operations were ongoing in the central city, with regional governor Serhii Lysak adding that at least 50 people were injured.
Zelenskyy said the attack proved Moscow was not interested in peace.
"Russian strikes every day," he said.
"People die every day. There is only one reason why this continues: Russia does not want a ceasefire, and we see it. The whole world sees it.
"Every missile, every strike drone proves that Russia only wants war. And only from the pressure of the world on Russia, from all efforts to strengthen Ukraine, our air defence, our forces - only on this depends when the war will end."
