At least five people were killed, Ukrainian President Volodymyr Zelenskyy said.

Russia launched an attack on Kyiv and other Ukrainian cities early Tuesday, continuing its escalated large-scale attacks on residential areas, local officials said.

Air raid sirens in Kyiv began to sound just before 6 a.m. The attacks, which also hit Kharkiv, lasted about four hours, with Russia launching about a dozen ballistic missiles and about 35 Iranian-made drones, Ukrainian officials said.

At least five people were killed and 101 were injured in Tuesday’s attacks, Ukrainian President Volodymyr Zelenskyy said.

“Putin is ringing in 2024 by launching missiles at Kyiv and around the country as millions of Ukrainians again take shelter in freezing temps,” U.S. Ambassador Bridget A. Brink said on social media.
