U.S. releases 4th prisoner this month from Guantánamo Bay, leaving 26 at the American facility in Cuba

The Pentagon said Monday it had repatriated to Tunisia one of the remaining detainees at the Guantánamo Bay military prison.

Ridah Bin Saleh al-Yazidi was sent there the day it opened, Jan. 11, 2002, under President George W. Bush, according to the New York Times.

He was found eligible for transfer "by a rigorous interagency review process", a Defense Department statement said.
