-- Investigators believe that an explosion aboard a plane in Somalia was likely caused by a small bomb that was placed inside of a laptop, sources familiar with the probe said.
The A-321 jetliner made an emergency landing and returned to the airport, but two passengers were hurt. It’s believed one person may have been sucked out of the plane through a relatively small hole left by the explosion -- possibly the bomber.
Many of the passengers on the flight were originally scheduled to be on a Turkish Airlines flight but the flight was canceled "due to operational reasons" and bad weather, according to Turkish Airlines spokesman Yahya Ustun.
An FBI spokesman declined to comment for this article, referring questions to Somali authorities.
