The United States on Thursday banned all flights of Pakistan International Airlines (PIA) with immediate effect.
The US Transport Department said in a statement that special permission given to PIA had been suspended due to safety concerns.
The move follows the grounding of 262 airline pilots in Pakistan over fake licences in a decision made by the Civil Aviation Authority of Pakistan.
PIA said on Thursday it would ground pilots with “dubious” licences.
As per sources, Kuwait Air has grounded at least seven Pakistani pilots and 56 engineers, while Qatar Airways, Oman Air and Vietnam Airlines have compiled lists of Pakistani pilots, engineers and ground staff.
The UAE’s Emirates airline has also put a halt on all Pakistani airline flights, barring them from using the airports for destination and transit flights.
