Nepals only international airport remained closed Friday after a Malaysian passenger plane with 139 people on board aborted its takeoff and skidded off the runway, officials said. Tribhuvan International Airport in Kathmandu said no one was injured when the Boeing 737 operated by Malindo Air skidded to the end of the runway Thursday night and was stuck in mud. All flights have been canceled since the accident with thousands of passengers waiting outside the terminal. The flight by the Malaysian carrier to Kuala Lumpur was accelerating on the runway when the pilots detected a problem and halted the takeoff, airport spokesman Prem Nath Thakur said. The jet skidded to a halt on grassland and came to a stop in mud about 30 meters from the runway. "All aboard are safe," Thakur said, adding that the cause of the problem was not immediately known. Malindo Air has regular flights linking Kuala Lumpur and Kathmandu. Last month, a Bangladeshi passenger plane crashed at the airport while attempting to land, killing 49 people on board.
