MOSCOW—At least eight people were killed, including seven children, when an attacker opened fire Tuesday at a school in the Russian city of Kazan, according to local authorities. A teacher was also reported to be among the dead and at least 20 people were injured and taken to the hospital, officials said.
A statement posted on the website of Kazan, capital of the largely Muslim republic of Tatarstan some 500 miles east of Moscow, said the four boys and three girls killed were eighth-graders and they were gunned down on the third floor of the school.
A 19-year-old man has been arrested and had in his possession a weapon officially registered in his name, the statement said. Possible accomplices had not yet been identified, authorities said.
An investigation is under way. Russia’s Investigative Committee, the country’s main investigations agency, said it had opened a criminal case in relation to the attack.
