Ukraine’s two largest cities came under heavy Russian missile attacks on Tuesday, killing one person and injuring dozens. Oleh Syniehubov, the governor of the Kharkiv region, said one person died and 41 were injured in Russian missile strikes that hit the center of Kharkiv city and other areas. In Kyiv, the capital, five areas of the city were hit in the strikes and at least 12 people injured, according to mayor Vitali Klitschko.

The barrage of the cities continued Russia’s escalated attacks on Ukraine in recent days that began on Friday with its largest single attack on Ukraine since the war started, in which at least 41 civilians were killed. The following day, shelling of the Russian border city of Belgorod that Russian officials blamed on Ukraine killed 25 people. Russia has struck back repeatedly since.
