The balloon was flying at 1,000 ft (300m) when it caught fire and exploded, plunging onto fields west of Luxor, officials said. One witness told the BBC people were jumping out of the balloon, "from about the height of a seven-storey building". Two people, including the balloon's pilot, reportedly survived the crash. According to Egyptian police, the victims include nine from Hong Kong, four from Japan, two from the United Kingdom, two from France and two from Egypt. Luxor lies on the banks of the River Nile and is home to some of Egypt's most famous pharaonic-era ruins.
