The following is a summary of the allegations against Hassan Attash found in publicly available US military documents. If US military documents about this prisoner are inaccurate or misleading then this summary will be as well. The introduction to this set of summaries explains some of the terms used below.
Hassan told US interrogators that he attended the Khaldan and Jihal Wahl militant training camps in Afghanistan.
Hassan admitted to delivering funds and letters to two commanders in Kandahar for KSM. The funds were to be used to start a military campaign against American troops in the Kandahar region.
Hassan admitted to participating in a plot to attack oil tankers in the Straits of Hormuz and off the coast of Yemen. Ahmed al Darbi claimed Hassan contacted him to arrange delivery of funds for the operation. Hassan later claimed he did not take an active part in any of the planning or execution of the boat attacks against American vessels.
KSM said that he told Hassan to deliver remote-control devices to Quetta for Abd al-Hadi al-Iraqi. Al-Hadi was preparing IED to use against US and coalition forces.
Hassan was captured in September 2002 in a series of raids by Pakistan’s ISI on a series of suspected Al Qaeda safe houses in Karachi, Pakistan. Journalist Andy Worthington says that Hassan was either 16 or 17 when he was captured. Hassan was later transferred to US custody. He arrived at Guantanamo in September 2004.
In December 2002 the United States ratified the “UN Optional Protocol on the Rights of the Child on the involvement of children in armed conflict” which says that signatories must ensure, “the physical and psychological reintegration” of child soldiers.
Hassan was recommended for prosecution by Obama’s Guantanamo task force in January 2010.
Hassan Attash has spent over 9 years at Guantanamo.
