The PIA plane was seized on the orders of a local Malaysian court, the Geo News report said citing sources as saying.
PIA had leased two aircraft, including the seized Boeing-777, from a Vietnamese company in 2015.
The plane was seized after passengers had already boarded the aircraft.
The aircraft’s 18-member staff also become stranded in Kuala Lumpur due to the seizure, and will now quarantine for 14 days as per protocols, the sources said.
In a Twitter post, the Pakistani flag carrier said: “The passengers are being looked after and alternate arrangements for their travel have been finalised.”
