Zubaydah eventually became involved in the jihad training site known as the Khalden training camp, where he oversaw the flow of recruits and obtained passports and paperwork for men transferring out of Khalden. He may also have worked as an instructor there. Although originally described as an al-Qaeda training camp, this alleged connection, which has been used as justification for holding Zubaydah and others as enemy combatants, has come under scrutiny from multiple sources, and the camp may have shut its doors in 2001 in response to an ideological division with al-Qaeda.
