Thirty-three people died after a 41-year-old man allegedly stormed into a Kyoto animation production studio Thursday and set fire to it by spraying a flammable liquid, local police and rescuers said.

In the fire that started at a studio of Kyoto Animation Co. in the city’s Fushimi Ward around 10:35 a.m., 36 others have been sent to hospitals for injuries. About 70 people were believed to have been working inside the three-story, 690-square-meter building at the time.
