Police say at least 12 people have died and many others are unaccounted for in a suspected arson attack at an animation studio in Kyoto.
Police say a man poured what appeared to be gasoline inside Kyoto Animation's studio and set fire to the building shortly after 10:30 am on Thursday.
They say about 70 people, mainly studio employees, were inside the building when the fire started.
Fire authorities say 36 people have been taken to hospital and one person has been confirmed dead.
They also say they are trying to confirm information that more than 30 people remain unaccounted for and 12 have been found without vital signs on the first and second floors of the building.
Police say they believe the suspect is a 41-year-old man, based on a driving license he was carrying. He was detained and is being treated for his injuries at a hospital. The man reportedly admitted as he was being taken to hospital that he spread the liquid around before setting it on fire.
Investigative sources cite witnesses who say the man was telling people to die as he started the blaze. They also say multiple knife-like objects were found at the scene but it is not known whether they belong to the suspect.
