 Russia's U.N. ambassador, who chaired Tuesday's Security Council meeting, blamed Ukrainian air defenses for the explosion at the children's hospital. That's a finding contradicted by a U.N. human rights monitor. The U.N. says more than 11,000 civilians across Ukraine have been killed and 22,000 injured since Russia's 2022 invasion. Health care facilities and medical workers have faced nearly 1,900 attacks.
