US President Donald Trump signed an executive order Jan. 30 to continue operations at the Guantánamo Bay detention center. The order states that the facility is "legal, safe, humane, and conducted consistent with United States and international law." Trump's new executive order not only allows for those detained currently to remain detained, but also allows for the US to transport new persons to the facility when lawful and necessary. Trump's order revokes the 2009 order from then-president Barack Obama that was intended to close the facility at Guantánamo and transfer detainees to other detention facilities, their home countries or to a third country. There are currently 41 detainees in custody at Guantánamo.

Military judge James Pohl ruled Jan. 19 that no wrongdoing occurred when he authorized the destruction of a CIA secret prison, or "black site," despite the fact that a protection order was in effect on any remains from the CIA black sites. Prosecutors, citing national security powers, obtained permission from the judge to give defense attorneys photographs and a diagram of the site as a substitute for preservation the actual facility. According to Pohl, defense attorneys failed to show that "the physical evidence is of such central importance to an issue that is essential to a fair trial, or that there is no adequate substitute for the physical evidence." According to the Miami Herald, from 2002-2006, prisoners at the black site were subjected to waterboarding, sexual abuse, and other forms of torture.

Eleven Guantánamo inmates filed a writ of habeas corpus (PDF) in the US District Court for the District of Columbia on Jan. 11, claiming that their indefinite detention is due to President Donald Trump's anti-Muslim stance. The inmates argue they can only be legally kept at Guantánamo if their individual circumstances show that they would otherwise return to the battlefield. However, the suit claims that Trump's declaration that all Guantánamo inmates will remain in the prison camp does not take into account any of their individual circumstances, but instead is based on Trump's antipathy toward Muslims. Some of the petitioners have been at Guantánamo for the entirety of its 16 years in use as a prison. Two of the detainees were in the process of being cleared for release under the Obama administration, before the Trump administration put a stop to the release process for all inmates. The petition states that the indefinite detentions violate the due process clause of the Constitution.

UN Special Rapporteur on Torture Nils Melzer issued a statement Dec. 13 calling on the US to end impunity for "perpetrators and policymakers responsible for years of gruesome abuse" at Guantánamo Bay and other detention facilities. Melzer urged US authorities to take action on the 2014 Senate Intelligence Committee Report, which found that the Central Intelligence Agency (CIA) deliberately misled Congress and the White House about information obtained using so-called "enhanced interrogation techniques" between 2002 and 2007. Melzer contends that the US us in violation of the Convention Against Torture by failing to prosecute instances of torture outlined in the Senate Report, "sending a dangerous message of complacency and impunity to officials in the US and around the world."

The US Court of Appeals for the District of Columbia Circuit ruled (PDF) Aug. 16 that Judge Scott Silliman should have recused himself in a case concerning multiple defendants who were charged with aiding in the 9-11 attacks. The petitioner, Khalid Sheikh Mohammed, argued that Silliman was biased in the matter and cited a 2010 comment in which Silliman called Mohammad and his co-defendants the major conspirators in th attacks. The court found that because Silliman "expressed an opinion that Petitioner is guilty of the very crimes of which he is accused," he manifested an "apparent bias" and thus should have recused himself. The court granted the petition seeking recusal of Silliman and vacated a decision (PDF) by the US Court of Military Commission to reinstate charges for "attacking civilians and destroying property in violation of the law of war" against Mohammad and his co-defendants.

The Canadian Minister of Foreign Affairs Chrystia Freeland and Minister of Public Safety and Emergency Preparedness Ralph Goodale issued a joint statement on July 7 apologizing to former Guantánamo detainee Omar Khadr for violating his rights under the Canadian Charter of Rights and Freedoms. Freeland and Goodale's statement read:

Attorneys for Guantánamo detainee Abu Zubaydah have filed a lawsuit against the two psychologists, James Mitchell and Bruce Jessen, who developed the harsh interrogation techniques used by the CIA, including waterboarding and sleep deprivation. The UK human rights group Reprieve announced the case on June 7. The attorneys are seeking to subpoena the psychologists in order to uncover evidence about the torture that allegedly went on in Poland. According to US law, a federal district court may "order discovery of documents and testimony for use in a foreign proceeding from any person who resides or is found in the court's district." The case will be heard in the US District Court for the Eastern District of Washington. The CIA had detained the plaintiff in a secret Polish prison from 2002 to 2003 on suspicions that he was a "facilitator" for al Qaeda. Zubaydah has been held at Guantanamo since 2006. In April 2016 a federal judge ruled that another lawsuit against the same psychologists with different plaintiffs could proceed.

US warplanes and drones struck supposed al-Qaeda targets in Yemen for a second straight day March 3, killing at least 12 suspected militants, according to local officials. The Pentagon said it had carried out more than 20 strikes overnight targeting al-Qaeda positions in the southern provinces of Shabwa and Abyan, and the central province of Baida. In the latest strikes, US fighter jets hit three houses in the Yashbam Valley before dawn, one of them reportedly the home of al-Qaeda's Shabwa province commander, Saad Atef, local sources said. Tribal sources said that several civilians were wounded, including women and children. One resident said it had been a "terrifying night." (Middle East Online, Al Jazeera, BBC News)
