Mohammed Haydar Zammar ( Muḥammad Ḥaydar Zammār) (born 1961) is a Syrian-German militant who served as an important al-Qaida recruiter, Zammar reportedly boasted that he personally recruited Atta and other hijackers into al-Qaida. Zammar also met frequently with Mounir El Motassadeq around this time.

In 1998 Germany intensified their surveillance of Zammar. He was trailed, his phone was tapped and his calls were recorded. German authorities shared this information with the CIA, including Zammar's phone conversations with hijackers Marwan al-Shehhi, Mohamed Atta, Ramzi bin al-Shibh, and Said Bahaji.

Atta, Shehhi, and bin al-Shibh formed the Hamburg cell in November 1998, and Zammar is reported to have been a frequent visitor. Atta became the group leader, and Zammar was seen as a valuable conduit for international contacts.

In the Summer of 1999, U.S. intelligence discovered that Zammar was in direct contact with one of bin Laden's senior operational coordinators. The U.S. apparently did not share this information with German intelligence. Zammar is also known to have met frequently with Said Bahaji in Germany in 2000.

Capture

On October 27, 2001, Zammar traveled to Morocco. Not long afterwards, he was arrested by Moroccan police with the assistance of the U.S. Although he was a German citizen and under investigation by Germany, German intelligence only learned about the arrest from the newspapers in June 2002.

Instead of being deported to the U.S. or Germany, Zammar was secretly sent to Syria for indefinite detention in the notorious Far'Falastin detention center in Damascus. Time Magazine reported: "U.S. officials in Damascus submit written questions to the Syrians, who relay Zammar's answers back. . . State Department officials like the arrangement because it insulates the U.S. government from any torture the Syrians may be applying to Zammar."

On December 15, 2005, it was officially confirmed that German Bundeskriminalamt federal police officers had on at least one occasion participated in Zammar's interrogation in Syria; it was claimed that these officers were unaware of the conditions at the prison. This seems doubtful given that it was widespread knowledge in the intelligence/international politics community, but if referring specifically to the treatment of Zammar, it may or may not be true; it is not known whether Zammar's interrogation by Syria or other parties did or does involve torture and if so, to which extent.

According to Amnesty International, Muhammad Haydar Zammar was a victim of the US-led renditions programme who was convicted in February 2007 after an unfair trial before the Syrian Supreme State Security Court. Amnesty also alleged that he was held in pre-trial detention for almost five years, much of it in incommunicado and solitary confinement, at the notorious Palestine Branch of Military Intelligence in Damascus. During his detention he was tortured and otherwise ill-treated. In June 2007 the UN Working Group on Arbitrary Detention stated that Muhammad Haydar Zammar was detained arbitrarily and called upon the Syrian authorities to "remedy the situation". Amnesty International was not aware of the authorities having taken any steps to do so.

Release

Zammar was released as part of a prisoner exchange between the Islamist Syrian rebel group Ahrar al-Sham and the Syrian Government in September 2013. A member of the negotiating team told Der Spiegel that days after being released, Zammar travelled to the Syrian city of Raqqa and joined the Islamic State (IS). He reportedly organised for funds to be sent to the Sinai-based militant group Ansar Bayt al-Maqdis, and negotiated for the group to swear allegiance to IS.

Recapture

Zammar was recaptured by members of the Kurdish People's Protection Units in March 2018 near the village of Darnij in Deir al-Zour. , he is being held in a prison in Qamishli, Northern Syria, from where he gave an interview to The Washington Post.
