There were no survivors among the 152 people aboard a jetliner that crashed on Wednesday in fog and torrential rain near Islamabad, Pakistani officials have said.

Rescuers worked in heavy rains to recover the bodies of 146 passengers and six crew members from the Airblue jetliner wreckage as officials began trying to determine why the Pakistani airline's 10-year-old Airbus 321 crashed.

The New York Times has reported that the dead included two Americans.

U. S. President Obama issued a statement expressing condolences to the families and friends of all who died.

He said, "Our thoughts and prayers go out to all of those touched by this horrible accident"

Thursday will be a national day of mourning in Pakistan.

Pervez George, a spokesman for the country's civil aviation authority, said that the Karachi-to-Islamabad flight crashed while trying to land.

The Times further said that the cause of the crash had not been determined. While Pakistani officials had not ruled out a terrorist attack, the focus was on the deteriorated weather conditions at the time.

According to the reports of CNN, interior Minister Rehman Malik said the plane was at 2,600 feet as it approached Islamabad but went back up to 3,000 feet before crashing. (With Inputs from Agencies)
