At a press conference with Ukrainian President Volodymyr Zelensky, Polish Prime Minister Donald Tusk condemns Russia's strike on a children's hospital in Kyiv, with dozens killed in missile attacks across the country. "There are no words, documents, or political declarations that would suffice, on the one hand, to condemn the aggressor and, on the other hand, words that would suffice as signs of solidarity and assistance," Tusk says. Russia struck cities across Ukraine on Monday with a missile barrage that killed 31 people and heavily damaged the children's hospital. IMAGES AND SOUNDBITES
