The Center for Constitutional Rights (CCR) said in a press release shared with Middle East Eye that Shaqawi al-Hajj, 51, was flown to Oman this week after spending nearly 21 years in prison. He also spent two years at CIA sites.

The transfer was initially slated for October 2023 but the 7 October 2023 Hamas-led attack on southern Israel and Israel’s subsequent war on Gaza delayed the transfer, according to an admission from US officials in May last year.

“He was part of a transfer of a group of 11 Yemenis cleared for release, bringing the Guantanamo population to 15 men, six of whom are uncharged, including three men also cleared for transfer,” the press release said.

The CCR says that Hajj was never charged with a crime and was subject to “physical and psychological coercion” at CIA sites before transferring to Guantanamo in 2004. He attempted to hurt himself multiple times during his incarceration, according to the centre.

“Our thoughts are with Mr Al Hajj as he transitions to the free world after almost 23 years in captivity. His release is hopeful for him and for us. We are grateful to Oman and to the individuals in the administration who made this transfer happen, and to the many people over the years whose work and advocacy paved the way for this moment,” said Pardiss Kebriaei, a senior staff attorney at CCR who represents Hajj.
