Why is Guantanamo Bay prison still open 20 years after 9/11?

The fate of 39 detainees who are still being held rests with US President Joe Biden, who has pledged to close the prison.

Moath al-Alwi was captured by Pakistani forces near the Afghanistan border in December 2001 and given over to the United States military. A Yemeni national, al-Alwi has said he was fleeing for safety, not a fighter, when he was abducted and sold to the US military, which in January 2002 transported him across the world to a tropical prison camp at the US Navy base in Guantanamo Bay, Cuba. In the nearly 20 years since, the notorious military prison at Guantanamo has become a symbol of US human rights abuses. Many detainees – mostly Muslim men – were tortured or held for years and even decades without charges, trials or basic legal rights.
