A Russian drone and missile strike near Odesa damaged port infrastructure, a grain silo and an abandoned hotel and injured one person, as attacks on Ukraine killed four civilians and wounded 13 in the past day, Ukrainian officials said Monday. Ukraine’s air force reported downing all Russian drones overnight, but one of 12 Kalibr missiles and two P-800 Oniks cruise missiles apparently made it past air defenses the day after the war in Ukraine entered its 20th month.

In the south, Russian forces dropped bombs and launched six heavy artillery strikes on Kherson, destroying a school and factory and damaging residential buildings. Two people were killed and two others were injured by bombs that hit the city of Beryslav. A man was killed in the neighboring village of Lvove. To the east of Donetsk region, Russians attacked residential areas of 10 cities and villages, killing two.
