MOSCOW—A gunman attacked a school Tuesday morning in the Russian city of Kazan, sending students running out of the building as smoke poured from its windows. At least nine people were killed—seven eighth-grade students, a teacher and another school worker—and 21 others were hospitalized, Russian officials said.
Footage released by Russian media outlets showed students dressed in black and white running out of the building. Another video depicted shattered windows, billowing smoke and sounds resembling gunshots in the background. Dozens of ambulances lined up at the school’s entrance after the attack and police fenced off access to the building.
