An investigation is underway as to what caused an Air India airliner carrying 230 passengers and 12 crew members to crash shortly after takeoff on Thursday.

The first meeting of the high-level multi-disciplinary committee set up by the government to look into the Ahmedabad plane crash will be held on Monday here, sources said.

One of the strongest pieces of evidence under review is a CCTV clip that shows the takeoff and the crash of the plane.
