Fireworks explosion injures 60 in Japan Fireworks explode in Hiroshima. Another fireworks display was cancelled in Kyoto after an explosion occurred, resulting in 60 people being sent to hospital. MORE than 60 people have been injured by an explosion probably caused by a gas cylinder just before a fireworks display in Japan's Kyoto prefecture. Public broadcaster NHK said the cylinder was close to a drinks and snacks counter put in place for a grand fireworks festival which takes place each summer in Japan. An explosion was heard around 7:25pm (8:25pm AEDT) and the counter and other objects were thrown in the air as a fire started and people fled, according to accounts and photographs posted on the Internet. Sixty-one people were taken to hospital, Kyodo News reported, including two seriously injured with burns over their entire bodies. It said the fireworks show, which attracted about 110,000 spectators last year, was cancelled after the blast. Personal belongings were strewn across the area as investigators searched for clues.
