Russia launched exploding drones that killed at least four people at a student dormitory near Kyiv before dawn Wednesday, just hours after Japan's prime minister left the Ukrainian capital following a show of support for the country, and as Chinese leader Xi Jinping left Moscow after discussing his proposal for ending the war, was rejected by the West as a non-starter.

A high school and two dormitories were partially destroyed in an overnight drone attack in the city of Rzhyshchiv, south of the Ukrainian capital, local officials said. It wasn't clear how many people were in the dormitories at the time.
