ISLAMABAD — A Pakistani passenger jet with 127 people on board crashed into wheat fields today as it was trying to land in a thunderstorm at an airport near the capital Islamabad. Sobbing relatives of those on the flight flocked to the airport, and officials said there appeared to be no survivors.

Emergency workers used flashlights to search among the smoldering wreckage of the fuselage, smashed seats and body parts for any sign of life at the crash site, which was just a few miles from the Benazir Bhutto International Airport. One rescue official asked villagers to bring him sheets to cover the dead.

The aircraft was a Boeing 737-200 operated by Bhoja Air, a domestic carrier that has just four planes and only resumed operations last month after suspending them in 2001 due to financial difficulties. The flight was traveling from the country’s largest city of Karachi to the Pakistani capital, officials said. It was the airline’s first evening flight from Karachi, according to a Bhoja Air official.

Wreckage, including smashed seats, clothes and jewelry belonging to passengers, was spread out over a half-mile-wide area.
