On Dec. 31 the US Department of Defense said five prisoners at Guantánamo Bay will be released to the government of Kazakhstan as part of an effort by the Obama administration to expedite the closing of the facility. An interagency Guantánamo Review Task Force conducted a comprehensive review of the cases of Asim Thabit Abdullah al-Khalaqi, Muhammad Ali Husayn Khanayna, Sabri Muhammad Ibrahim al-Qurashi, Adel al-Hakeemy and Abdullah Bin Ali al-Lufti. The men were unanimously approved for transfer. After the transfer, 127 detainees will remain at Guantánamo Bay.

The US Department of Defense on Dec. 27 announced the repatriation of four Guantánamo Bay detainees to Afghanistan. The prisoners—Shawali Khan, Khi Ali Gul, Abdul Ghani and Mohammed Zahir—were released after a review of their cases. Although originally detained on suspicion of being associated with groups such as the Taliban and other terrorist organizations, they had been cleared for transfer for quite some time. They were considered "low-level detainees" and not security risks in their home country. With the release, the population of Guantánamo has been reduced to 132 prisoners. The release of the four men is part of an effort by the Obama administration to close Guantánamo Bay, despite restrictions in the latest defense spending bill, which President Obama signed Dec. 19 with a statement that expressed dissatisfaction over the provisions.

The so-called "enhanced interrogation techniques" employed during the Bush administration were "ineffective," according to a long-awaited report (PDF) released Dec. 9 by the US Senate Select Committee on Intelligence. According to the report, the Central Intelligence Agency (CIA) deliberately misled Congress and the White House about information obtained using "enhanced interrogation techniques" between 2002 and 2007, which were more brutal than the public was led to believe. The more than 600 pages of materials that were released to the public are based on millions of internal CIA documents and took over five years to produce. The full report, totaling more than 6,700 pages, remains classified but has been shared with the White House.

The US Department of Defense (DoD) on Dec. 8 announced the transfer of six detainees from the Guantánamo Bay detention center to Uruguay. This move is the result of a 2009 Executive Order issued by President Obama instructing the Guantánamo Bay Review Force to review these cases. The decision to transfer the detainees was unanimous amongst all parties constituting the inter-agency task force (PDF): the DoD, Department of Justice, State Department, Department of Homeland Security, Office of the Director of National Intelligence and Joint Chiefs of Staff. The six detainees are Ahmed Adnan Ahjam, Ali Hussain Shaabaan, Omar Mahmoud Faraj, Jihad Diyab, Abdul Bin Mohammed Abis Ourgy and Mohammed Tahanmatan. The men comprise four Syrians, a Tunisian and a Palestinian, and they will be granted refugee status by the Uruguayan government. Secretary of Defense Chuck Hagel informed Congress of the US' intent to transfer and its accordance with statutory requirement. After this transfer, there will be 136 detainees left at Guantánamo Bay.

The US Department of Defense (DoD) announced Nov. 20 the transfer of five detainees from the detention facility at Guantánamo Bay. Three are being transferred to the country of Georgia, while Slovakia has accepted the transfer of two more detainees. In 2009 the Guantanamo Review Task Force, composed of six agencies, approved the transfers after considering factors such as security issues. Congress imposed restrictions on dozens of approved releases, including prohibiting any detainees from being sent to the US, but many restrictions were relaxed last December. A total of 143 prisoners remain at Guantanamo, and 74 of these have also been cleared for a future transfer.

A study by UK-based Institute for Economics and Peace (IEP) finds there were nearly 10,000 terrorist attacks in 2013, 44% more than the year before. The number of terrorism-related deaths climbed 61%—from 11,133 in 2012 to 17,958 in 2013. The Global Terrorism Index reported four groups dominated the attacks: ISIS, Boko Haram, al-Qaeda and the Taliban, collectively responsible for 66% of the fatalities. Iraq was the country most affected by terrorism, with 2,492 attacks that killed more than 6,300. The report found that ISIS was responsible for "most" of the deaths in Iraq. The next top countries were Afghanistan, Pakistan, Nigeria and Syria. IEP produces the report from the Global Terrorism Database compiled by the National Consortium for the Study of Terrorism and Responses to Terrorism (START), at the University of Maryland. (Yahoo News, Nov. 18; AP, Nov. 17)

A judge for the US District Court for the District of Columbia on Oct. 3 ordered (PDF) the public release of 28 videos showing the forced feeding of Guantánamo Bay detainee Wa'el Dhiab. Dhiab, a Syrian citizen, has been held at Guantánamo since 2002 and has been on a long term hunger strike in protest of his detention. US District Court Judge Gladys Kessler rejected the US Navy's arguments that releasing the tapes would aid detainees in thwarting security measures, produce propaganda, and violate the Geneva convention. She found instead that the decision to disclose classified information lies with the judiciary rather than the executive branch stating that:

Australian citizen David Hicks filed a motion (PDF) to dismiss his conviction in the US Court of Military Commission Review on Aug. 20 after pleading guilty in 2007 for war crimes that took place before 2001 in exchange for his release. Hicks was captured in Afghanistan shortly after Sept. 11, 2011, and brought to the detention facility in Guantánamo Bay the day that it opened. The Center for Constitutional Rights (CCR) and co-counsel Joseph Margulies filed a motion asking the military commission to vacate Hicks' conviction for "material support for terrorism," following the US Court of Appeals for the DC Circuit's 2012 decision in Hamdan v. United States (PDF), which held that material support for terrorism is not a war crime and, thus, is beyond the jurisdiction of military commissions. Hicks' original appeal in November was stayed pending the ruling in Al-Bahlul v. United States (PDF), which similarly held last month that material support is not a war crime and cannot be tried by military commission. Hicks was the first person to be convicted in a military commission. After his release from Guantánamo, Hicks returned to Australia under a one-year gag order that prohibited him from speaking to the media. As part of his plea, he was also prevented from taking legal action against the US and required to withdraw allegations that the US military abused him.
