The CAA had temporarily restored Pakistani airspace for commercial aviation on Thursday, allowing some flights to depart as air traffic over the country remained suspended amid escalating tensions with India.

The three flights included Emirates flight number EK637 from Peshawar to Dubai, Air Arabia G9825 from Peshawar to Ras Al Khaimah, and Qatar Airways QR601 from Peshawar to Doha.
