UPDATE at 1:55 p.m. EST:
NPR's Julie McCarthy, reporting from the scene, says civil defense personnel "have not pulled out any survivors."
It's a grim scene here," she says.
"It's dark. The only lights we're getting here are from the ambulance[s]," she says. "It's crawling now with civil defense [personnel] who are sort of picking through this wheat field to find what remains of the plane."
UPDATE at 11:50 a.m. EST:
The Associated Press quotes Defense Minister Chaudhry Ahmed Mukhar as saying the 737-200 went down in a farm field of a relatively unpopulated area just a few miles from the international airport in Islamabad.
Mukhar said it was unlikely that anyone had survived.
Pakistani television showed wreckage of the plane, including parts that appeared to be the engine and the wing up against a small building, AP says.
UPDATE at 11:00 a.m. EST:
Reuters cites state television as saying "all hospitals in Islamabad and the nearby city of Rawalpindi had been put on high alert after the crash."
