Trabelsi had traveled to Afghanistan and met Osama bin Laden on several occasions. In 2001, Trabelsi was suspected of planning the US embassy terrorist attack in Paris which was uncovered and stopped. He is said to be the designated suicide bomber, and was to wear a business suit to conceal the strapped bomb onto himself before walking into the embassy.
Trabelsi was arrested in an apartment, in Uccle near Brussels, Belgium on 13 September 2001. He was also implicated by BritonSaajid Badat, who alleged that both of them had conspired with Richard Reid supposedly to blow up two US-bound airliners using shoe bombs simultaneously.
