US President Barack Obama on April 30 renewed his pledge to make an effort to close the detention center at Guantánamo Bay. At a news conference, Obama was asked about the ongoing hunger strike, now involving 100 of the 166 detainees. He responded, "Well, it is not a surprise to me that we've got problems in Guantánamo, which is why when I was campaigning in 2007 and 2008, and when I was elected in 2008, I said we need to close Guantánamo. I continue to believe that we've got to close Guantánamo." He went on to say:

US authorities have engaged in the torture of detainees, and the nation's "highest officials" bear some of the responsibility, according to a report (PDF) released on April 16 by the Constitution Project, a bipartisan legal advocacy and watchdog group. The Project's Task Force on Detainee Treatment was established after US President Barack Obama announced in 2009 that he opposed a proposal by Senate Judiciary Committee Chairman Patrick Leahy to set up a "truth commission" to investigate controversial actions of the Bush administration, including justifications for the Iraq war, warrantless wiretapping and detainee treatment. The task force members reached their conclusions after a two-year process, which included examination of public records and interviews with former detainees, military and intelligence officers, interrogators, and policymakers.

Military guards at Guantanámo Bay fired four "non-lethal" rounds at hunger-striking detainees the morning of April 13, as the facility commander forced them from a communal area into single cells. Some of the detainees used "improvised weapons" to resist being moved, according to a Department of Defense news release. No guards or detainees were reported to be seriously injured. Currently, 43 detainees are on hunger strike; 13 of those are being force-fed. Yet the military denies that it is attempting to break the strike. "Detainees may continue to hunger strike," but medical staff will now be able to monitor their condition, said Navy Capt. Robert Durand of Joint Task Force Guantanamo. He said the move to single cells was taken "to ensure that detainees are not being coerced by other detainees to participate in the hunger strike."

Italian president Giorgio Napolitano on April 5 pardoned US Air Force Colonel Joseph Romano of his conviction related to the US Central Intelligence Agency's abduction and "extraordinary rendition" of Egyptian cleric and terror suspect Osama Moustafa Hassan Nasr AKA Abu Omar. Joseph Romano was security chief of northern Italy's Aviano air base where Nasr was abducted prior to being flown to Egypt. Nasr was seized on the streets of Milan in 2003 by CIA agents with the help of Italian operatives, then allegedly transferred to Egypt and tortured by Egypt's State Security Intelligence before being released in February 2007. The US Department of Defense welcomed the news of Napolitano's pardon.

UN High Commissioner for Human Rights Navi Pillay on April 5 called for US authorities to close down the Guantánamo Bay prison camp, emphasizing the continued indefinite incarcerations of many detainees as a clear violation of international law. Of the 166 detainees in Guantánamo, about half have been cleared for transfer, either to home countries or third countries for resettlement, while only nine of them have actually been charged or convicted of crimes. Pillay stressed that those who have been cleared for release must be released immediately, claiming the US government's continued detention of these individuals is a violation of the International Covenant on Civil and Political Rights (PDF). The High Commissioner also expressed concern about the National Defense Authorization Act of 2013, which she says has created obstacles for the closure of Guantánamo as well as for the trials of detainees in civilian courts.

Approximately 250 Yemeni demonstrators gathered April 1 in front of the US Embassy in Sanna to demand the release of Yemeni detainees held at Guantánamo Bay. According to media sources, 90 out the 166 remaining Guantánamo detainees are Yemeni, and several have been detained for more than a decade. Protesters reportedly decried conditions at the prison, citing reports of inhumane treatment, water deprivation and forced feeding. Protesters also held up photos of their detained relatives and denounced treatment allegedly leading to several suicides, including that of Salah Al-Salami, who committed suicide while in detention in 2006. The protest prompted dispatch of the Yemeni military. Among the Yemeni detainees is Abd al-Rahim al-Nashiri, who is accused of bombing the USS Cole while it was in port in Yemen in October 2000.

Human rights lawyers on March 26 filed an emergency motion (PDF) in the US District Court for the District of Columbia alleging that guards at Guantánamo Bay have denied drinking water and sufficient clothing to a Yemeni prisoner. The motion was filed only a day before a fact-finding visit to the US detention center in Cuba by the International Committee of the Red Cross (ICRC), and the lawyers contend that such treatment is being used to undermine an ongoing hunger strike by Musa'ab Omar al-Madhwani and 30 additional inmates.

The US gave full control of Bagram Prison to Afghanistan on March 25, winding down the US military presence in the country. President Hamid Karzai sought to regain control of the detention center in efforts to reclaim sovereignty over the country, as the US prepares to withdraw troops from Afghanistan. The US was concerned that turning over the prison would put the secure detention of suspected Taliban and al-Qaeda members at risk. The official handing over of control to Afghan authorities took place after an agreement was reached during a phone call between US Secretary of Defense Chuck Hagel and Karzai on March 23. US Secretary of State John Kerry made an unannounced visit to Afghanistan in an attempt to strengthen the relationship between the two countries.
