US government sources: Al Shabaab was behind a suspected bomb attack on a Somali passenger plane

Investigators believe a bomb most likely caused the explosion aboard a plane that was forced to return to the Somali capital of Mogadishu for an emergency landing on Tuesday, two US government sources said on Wednesday.

Investigators also suspect the Al Shabaab jihadist group was behind the attack, although no organization has taken credit for the apparent bombing.

There was no immediate comment from Al Shabaab, which has waged a gruesome insurgency against the Western-backed Somali government and a multinational African Union military force.

One person died Tuesday when the Daallo Airlines Airbus A321 carrying 74 passengers was forced to return after a blast tore a hole in the fuselage. Local authorities in the Balcad area, about 30 kilometers north of Mogadishu, said the body of a man, believed to have been sucked out of the plane, was found in the area.

An unidentified man was sucked out of a passenger jet at 14,000 feet after a suspected bomb blasted a hole through the side of the fuselage just five minutes after the Airbus A321 took off from Mogadishu. 

Eyewitnesses claim the badly burned body of an elderly man fell to the earth about 15 miles away from the airport at the time of the blast. 

AIrline officials claim two people were injured by the blast which punched a hole in the aluminum fuselage about six foot by three foot in size.
