The US on Friday repatriated a Guantanamo Bay prisoner to his home country of Afghanistan after a federal court ruled the US no longer has a legal basis to detain him.

The Pentagon announced the transfer of Asadullah Haroon al-Afghani from Guantanamo Bay prison after the US District Court of Columbia's ruling that there was no longer any legal basis to justify his continued detention.

Al-Afghani, also known as Gul, was not charged with any war crimes and held for 15 years without a trial.

"Previously, on October 7, 2021 the Periodic Review Board (PRB), a body comprised of senior career officials from the Departments of Defense, State, Justice, and Homeland Security; and the offices of the Director of National Intelligence and the Chairman of the Joint Chiefs of Staff; determined Mr. Gul to be eligible for transfer," said Pentagon in a statement.

"The United States thanks the Government of Qatar for its assistance in this matter," it added.
