MOGADISHU, Somalia (AP) — It was a bomb that blew a hole in a jetliner, killing one person and forcing the plane to make an emergency landing on Tuesday in Somalia's capital, Mogadishu, a Somali official said Saturday. "Experts who were investigating the cause of the blast in the plane concluded that a bomb was the cause," said Ali Jama Jangali, Somalia's transport minister at a press conference in Mogadishu. Six people have been arrested in connection with the blast after examinations of CCTV images in the airport, a senior Somali intelligence official told the Associated Press. Had the blast occurred at a higher altitude, it could have led to explosive decompression on the plane, which might have caused more severe structural damage, and would have forced a more rapid descent because of limited supplies of oxygen to the passengers. After the explosion, passengers put on oxygen masks and air could be heard rushing thought the hole in the fuselage, according to a video taken by a passenger.
