Such was the force of the crash that the plane was said to have virtually disintegrated with few of the bodies of the victims recovered intact.
Health officials said DNA tests would be the only way to identify many of the remains.
Rescue worker Arshad Javed told the AFP news agency of horrifying scenes at the crash site.
"All we could see were charred hands or feet. I collected two heads, two legs and two hands in a bag.
"We shouted if anyone was there alive, but heard no voice," he said.
In a statement, Yousuf Raza Gilani, Pakistan's prime minister, "expressed grief and sorrow over the tragic incident" and offered prayers for passengers who were killed.
"The federal cabinet declared one day national mourning because of this tragic incident. The prime minister called off the cabinet meeting until next week in the wake of this tragic incident," Gilani's office said in the statement.
Qamar Zaman Kaira, the information minister, announced compensation of $5,800 for families of the victims.
