Mohammed Haydar Zammar

His reasons remain unclear.

At the Al-Quds Mosque, a preacher named Mohammed Haidar Zammar praises violent jihad to anyone who will listen.

After nine eleven, Zammar reportedly took credit for pushing the group toward Afghanistan.

By 1999, Atta, bin al-Shibh, and al-Shehhi share an apartment at fifty-four Marienstrasse.

Specifically, Mohamed Galeb Kaleji Zuladi, or Abu Talha, the brother-in-law of Osama bin Laden, who was one of Reagan's freedom fighters in 1989, sent money to Mahmoud Darqaz Ali Import-Export Company.

Mahmoud Darqaz Ali was to Marwan al-Sheikhi, the suicidal pilot who hit the South Tower, what Mohammad Zammar was to Mohammad Atta, the suicidal pilot that hit the North Tower.

And he knew them both.

The Spanish judge, Baltazar Garzon, deemed him Al-Qaeda's chief financer.
