(Reuters) -Russian forces staged a "massive" drone attack on Sunday on Kharkiv, Ukraine's second-largest city, killing one person and injuring at least four, officials said.
"There is a massive attack on Kharkiv," Mayor Ihor Terekhov wrote on the Telegram messaging app. He said one person was killed in the central Shevchenkivskyi district of the city in northeastern Ukraine after a drone strike on a private house.
Emergency crews were dispatched to the area.
Kharkiv, located 30 km (18 miles) from the Russian border, withstood Russian attempts to capture it early in the more than 3-1/2-year-old war and has since been a frequent target of attacks.
