New data released Monday showed that an additional ex-Guantanamo Bay prisoner has returned to fight with militants since his release. The Office of the Director of National Intelligence’s semiannual report showed that of the 144 detainees transferred after President Obama took office in January 2009, seven were have known to engage in terrorism activites. Data released in July 2015 showed six detainees. Ibrahim al-Qosi, a former cook and driver for Osama bin Laden, was repatriated to Sudan in 2012 and appeared in a propaganda video released by by al Qaeda’s Yemeni branch in December 2015. The report also showed that 12 former inmates released under Obama were suspected of returning to the battlefield—a number that has doubled in the last six months.
