At least 33 people are dead and dozens injured after a man set fire to an animation studio in the Japanese city of Kyoto, officials say.

Police said the 41-year-old suspect broke into the Kyoto Animation studio on Thursday morning and sprayed petrol before igniting it.

The suspect has been detained and was taken to hospital with injuries.

Japan’s Prime Minister Shinzo Abe said the incident was “too appalling for words” and offered condolences.

Kyoto Animation, known as KyoAni, produces films and graphic novels and is well regarded by fans for the quality of its productions.
