Three passengers, including a couple, suffered heart attack while another woman died on a Pakistan International Airlines (PIA) flight from Jeddah to Islamabad, according to media reports on Monday.
The PIA's PK-742 flight, which had around 225 passengers on board, made an emergency landing at Karachi Airport on Sunday after three passengers complained of severe chest pain, Pakistan Today said in a report.
An ambulance of the Civil Aviation Authority (CAA) with doctors and medical staff reached the tarmac at the Karachi airport to shift the critical passengers, The Express Tribune reported.
However, Mahala Bibi died before the plane had landed. The other two ailing passengers -- a married couple -- survived. Later, they were hospitalised.
