Three people were killed and 28 were wounded on Monday after Russian shelling hit the northeast Ukrainian city of Kharkiv, the regional governor said.
An official from the president's office said residential areas had been struck when Russia fired rockets from multiple rocket launchers at the city.
Russia, which invaded Ukraine on Feb. 24, denies targeting civilians.
