(AP Photo/Brennan Linsley, File) (Newser) – About one-quarter of former Guantánamo Bay detainees have been linked to terrorist activities since being released, according to a government report. Of the 598 men transferred out of the prison, 81 are confirmed to have taken part in terrorism or insurgency; 69 more are suspected of taking part in such activities. Of those 150, 67 have been killed or captured, the New York Times reports. Yesterday's report by the Office of the Director of National Intelligence was the first public look at what happened to the detainees, most of whom were released during the Bush administration. The Obama administration has transferred 66 prisoners, and five of those were linked to terrorist activity since leaving Guantánamo.
