Investigators believe a bomb probably caused the onboard explosion that forced an Airbus A321 to return to the Somali capital of Mogadishu for an emergency landing this week, U.S. government sources said on Wednesday.
One man was killed by the blast on Tuesday on the Daallo Airlines plane, officials said. Local authorities north of Mogadishu said the body of a man, believed to have been sucked out through the hole in the fuselage made by the blast, was found in their area.
The U.S. sources told Reuters on condition of anonymity that hard forensic evidence was lacking and no group is known to have claimed responsibility for the blast.
There was no immediate comment from al Shabaab, the Somali Islamist group that has waged an insurgency against the Western-backed Somalia government. It has carried out regular attacks on officials, government offices and civilian sites.
Daallo Airlines, which did not refer to a blast, said on its website that the “incident” that caused a hole in the fuselage happened 15 minutes into the flight.
“Pilots managed to land the aircraft back (in) Mogadishu Airport safely and without any further incident. All passengers, except one, disembarked safely,” it said, adding there was an investigation into “the cause of one missing passenger.”
Two passengers were taken to hospital with minor injuries, it added.
“The investigation goes on,” Somali civil aviation director Abdiwahid Omar said on the state radio website.
Local authorities said the body of a passenger was found in the Balcad area, about 30 km (19 miles) north of Mogadishu.
A police officer at Mogadishu airport said the body of the 55-year-old man was being brought to the capital. “He dropped when the explosion occurred in the plane,” the officer said.
Daallo Airlines, the national carrier of the tiny Horn of Africa country of Djibouti, had previously said the plane had 74 passengers on board.
Mohamed Hussein, an agent for Daallo, told Reuters on Tuesday that a “fire had erupted” on the flight. Images showed the plane with a hole in the fuselage over one wing.
A source familiar with the investigation said flammable objects are not usually put in that place in an aircraft.
Some reports suggested an oxygen bottle might have been involved, but safety experts say such bottles usually catch fire rather than explode. Photographs did not show significant damage to overhead panels where such bottles are usually kept.
Experts have praised the actions of the crew in landing the plane with so few casualties.
Daallo flies to several destinations in the Horn of Africa and the Middle East, according to its website.
