Pakistan's national carrier says one of its planes has gone missing after takeoff in the country's north with about 40 on board.

Daniyal Gilani, the spokesman for Pakistan International Airlines, says their ATR-42 aircraft carrying around 40 passengers and crew lost touch Wednesday with the control tower. He says all resources are being mobilized to locate the plane.

A local police official, Khursheed Tanoli, told state-run Pakistan Television that the plane went down in a village in the northwest and that rescuers are trying to reach the site of the crash.

No further details were immediately available.
