A Russian artillery attack on Ukraine's northeastern city of Sumy on Tuesday killed three people and injured 25, including children, the city council and the health ministry said.

Ukraine’s drone attack against Russian airfields was audacious and daring. But most of all, it was meticulously planned and flawlessly executed.
