Eleven Yemeni men imprisoned without charge or trial at the Guantánamo Bay detention center for more than two decades have just been released to Oman to restart their lives. This latest transfer brings the total number of men detained at Guantánamo down to 15. Civil rights lawyers Ramzi Kassem and Pardiss Kebriaei, who have each represented many Guantánamo detainees, including some of the men just released, say closing the notorious detention center “has always been a question of political will,” and that the Biden administration must take action to free the remaining prisoners and “end of the system of indefinite detention” as soon as possible.
