The Islamabad High Court, while dismissing a petition against the repatriation of Pak-Turk staffers, asked the petitioners to approach the interior ministry in this regard.

Management of the Pak-Turk network had moved the high court after the interior ministry ordered Turkish teachers at schools with alleged links to a Turkish cleric opposed to President Tayyip Erdogan to leave Pakistan.

The teachers and their families, totaling about 450 people, were given three days notice to leave, Pak-Turk International Schools and Colleges said in a statement late on Tuesday.

Pak-Turk educates more than 10,000 students in Pakistan and denies any affiliation with the cleric Fethullah Gulen, or his "Hizmet" movement.

Erdogan has accused Gulen, a former political ally, of being behind a coup attempt in July, and Turkey has previously asked Pakistan to shut down any groups in the country with links to the cleric.

"Pak-Turk International Schools and Colleges are deeply concerned over the abrupt decision of the government requiring the Turkish teachers, management and their family members...to leave the country within three days," the school said.

It added that staff members were asked to leave because of "non-approval of their requests for extension of visa".
