Turkey's military attache to Kuwait, Mikail Güllü, has been detained by Saudi Arabian officials after Ankara's request on Sunday, and will soon be extradited, Anadolu Agency reported on Monday.

According to reports, Güllü was detained after he left Kuwait and was taking a transit flight from Dammam Airport to Amsterdam following the failure of the coup attempt by the Gülenist Terror Organization (FETÖ) in Turkey.

Sources said that Güllü was expected to be appointed as the president of the Mechanical and Chemical Industry Corporation if the coup was successful.

Saudi authorities are currently working on Güllü's extradition, sources added.

Meanwhile, Saudi King Salman congratulated President Recep Tayyip Erdoğan on stopping the coup:

"His majesty congratulated him for the return to normal in Turkey and expressed the kingdom of Saudi Arabia's welcoming of the security and stability restored by the leadership of his excellency [Erdoğan] and the continuation of the activities of the Turkish government," the Saudi Press Agency said in a statement.
