ISLAMABAD, Pakistan — A Pakistani Air Force pilot died when his F-16 fighter jet crashed in the capital, Islamabad, on Wednesday during a training exercise for a military parade celebrating the country’s national day, officials said.

No other casualties were reported, though the crash site, Shakarparian Hills park in central Islamabad, is near museums and a sports stadium.

Pakistan’s Air Force said that it would investigate the cause of the crash and that it was too early to determine whether it was the result of a technical failure or a bird strike. The jet was performing a standard maneuver at a low altitude before it crashed, officials said. The pilot, Wing Commander Noman Akram, was unable to eject from the aircraft.

Videos posted online showed the jet dipping suddenly before disappearing behind a cluster of trees. The sounds of the crash could be heard moments later. Other clips showed the aftermath of an explosion that left many onlookers in disbelief.
