Fire swept through an animation studio in Japan on Thursday, killing at least 33 people and injuring scores more, with the cause suspected to have been arson after a man was seen shouting 'die' as he doused the building with petrol. Japan's prime minister, Shinzo Abe, tweeted that the fire in Kyoto was 'too appalling for words' and offered condolences to the victims. Police have taken a 41-year-old man into custody
