Mustafa al-Shamyri

Mustafa Abd al-Qawi Abd al-Aziz al-Shamiri is a citizen of Yemen who was mistakenly held in extrajudicial detention in the United States Guantanamo Bay detainment camp in Cuba. Al Shamiri's Guantanamo detainee ID number was 434. The Department of Defense reported that Al Shamiri was born on July 7, 1978, in Sanaa, Yemen. He was released and sent to Oman with nine other men on January 16, 2017.

At his 2015 Periodic Review Board hearing, the DoD acknowledged that they had realized that Shamiri had been held due to a misidentification. He was released and sent to Oman with nine other men, on January 16, 2017. In 2004, the United States Supreme Court ruled, in Rasul v. Bush, that Guantanamo captives were entitled to being informed of the allegations justifying their detention, and were entitled to try to refute them.

Office for the Administrative Review of Detained Enemy Combatants Combatant Status Review Tribunals were held in a 3x5 meter trailer where the captive sat with his hands and feet shackled to a bolt in the floor.

Following the Supreme Court's ruling the Department of Defense set up the Office for the Administrative Review of Detained Enemy Combatants.

Scholars at the Brookings Institution, led by Benjamin Wittes, listed the captives still held in Guantanamo in December 2008, according to whether their detention was justified by certain common allegations:
