A passenger plane with 152 people on board has crashed near the Pakistani capital.
Reports from the scene are sketchy but authorities were quoted as saying at least five people have survived. Other reports said no one had survived.
The aircraft caught fire after the crash, making rescue efforts difficult.
A search of the area continues but access is limited.
The Airbus 321 plane came down in bad weather in the forested Margalla Hills.
Operated by the private company Airblue, the plane had travelled from Karachi to Islamabad.
The military was called in to help in the rescue effort.
Local reports say there had been heavy monsoon rain in the area for at least a couple of days.
Airblue began operations in 2004 with a fleet of Airbus A320 and A321 aircraft.
