Night operations for international flights from Peshawar's Baacha Khan International Airport have been suspended due to security concerns.
The authorities took the decision after another incident of firing was reported on a PIA flight coming from a Gulf state before Eid.
The Pakistani Civil Aviation Authority (CAA) director general Mohammad Yousuf said: "The plane safely landed, however we have taken this decision in the best interest of passengers and also hope this temporary suspension of international flights during night-time will end soon and normal operations will resume soon, once the security is improved."
A total of PKR6bn ($60m) has been allocated for the airport's security arrangements, which are gradually being improved.
"All efforts are being made to make Peshawar airport safer for every arriving and departing passenger," added Yousuf.
Earlier this year, international airlines such as Emirates and Qatar Airways suspended operations to and from Peshawar following a firing incident on a PIA flight, which led to the death of a passenger.
Most of the flights from Gulf states arrive at night and because many Pakistanis travel to the region, Peshawar is also one of the most profitable routes for airline companies.
Meanwhile, the airport is installing communication systems that would help in expediting processes and facilitate air traffic controllers in transmitting and receiving the data.
Apart from that, the terminal building is also being expanded to improve passenger facilities.
