After hours of tense negotiations, two Libyans who hijacked a plane from Libya to Malta and threatened to blow it up surrendered peacefully Friday, allowing 118 passengers and crew to leave the plane before walking out themselves with the last of the crew. The hijacked Airbus A320 flight, operated by Afriqiyah Airways, was traveling from the Libyan oasis city of Sabha to Tripoli when it was diverted to Malta midmorning on Friday.
