Lists of former Guantanamo Bay detainees alleged to have returned to terrorism

Some former detainees who were held by the US at Guantanamo Bay detention camp have engaged in terrorism or militant activity since their release according to an unreleased Pentagon report. This is often referred to as Recidivism.

According to the Office of the Director of National Intelligence (ODNI), as of September 2016, 693 detainees have been transferred from Guantanamo Bay. According to th ODNI, 122 (17.6%) are 'Confirmed' as returning to terrorist or militant activities, while 86 (12.4%) are suspected by them of the same.

Guantanamo Bay detention camp is a joint military prison and interrogation camp under the leadership of Joint Task Force Guantanamo (JTF-GTMO) which has occupied a portion of the United States Navy's base at Guantanamo Bay, Cuba since 2002. The prison holds people suspected by the executive branch of the U.S. government of being al-Qaeda and Taliban operatives, as well as those no longer considered suspects who are being held pending relocation elsewhere.

As early as 2004, the US government claimed that detainees released from Guantanamo Bay detainment camp had returned to the battlefield. American officials, including former Vice President Dick Cheney, have claimed that detainees hid their real identities from interrogators, convincing them they were harmless to secure their release. Initially, government spokesmen claimed relatively small numbers of former Guantanamo captives had returned to the battlefield. In a press briefing on March 6, 2007 a "Senior Defense official" commented:

On Monday, May 14, 2007, Pentagon officials Joseph Benkert and Jeffrey Gordon repeated the assertion that thirty former captives had returned to the battlefield in testimony before the United States Congress. They identified six of the thirty by name. They offered the names of the three men previously identified: "Mullah Shahzada"; "Maulavi Abdul Ghaffar"; and Abdullah Mahsud. They tied "Mullah Shahzada" to Mohamed Yusif Yaqub, a Guantanamo captive who was listed on the official list. The other three names they offered were: Mohammed Ismail; Abdul Rahman Noor; and Mohammed Nayim Farouq.
