On May 1, 2006, Witness Against Torture and Clergy and Laity Concerned about Iraq organized a march to the US Mission to the United Nations to demand US compliance with the UN's recommendation that the detention center at Guantanamo be shut down. The anti-torture activists marched across midtown Manhattan before holding a prayer vigil at the entrance to the US Mission. The group of several hundred were risking arrest with the vigil, but the authorities allowed the presence to continue uninterupted.
