KYIV, Ukraine — A Russian strike on a nine-story building in the city of Sumy in northern Ukraine killed eight people and wounded dozens, an official said Sunday, as Russia launched a massive drone and missile attack described by officials as the largest in recent months.
Among the eight killed in Sumy, 40 kilometers (24 miles) from the border with Russia, were two children, said Ukraine's Minister of Internal Affairs Ihor Klymenko. More than 400 people were evacuated from the building.
The rescuers were checking every apartment looking for people who might be still in the damaged building.
''Every life destroyed by Russia is a big tragedy,'' said Klymenko.
The drone and missile attack, which targeted Ukraine's energy infrastructure, came as fears are mounting about Moscow's intentions to devastate Ukraine's power generation capacity ahead of the winter.
Also Sunday, President Joe Biden authorized for the first time the use of U.S.-supplied long-range missiles by Ukraine to strike inside Russia, after extensive lobbying by Ukrainian officials.
The weapons are likely to be used in response to North Korea's decision to send thousands of troops to support Russia in the Kursk region where Ukraine mounted a military incursion over the summer.
It is the second time the U.S. has permitted the use of Western weapons inside Russian territory within limits after permitting the use of HIMARS systems, a shorter-range weapon, to stem Russia's advance in Kharkiv region in May.
