From your Panama Canal article:
"While there is no direct evidence linking the canal with a specific threat, officials worry it could be a likely target.
In April 2001, a suspected al-Qaida figure identified as Adnan Gulshair El Shukrijumah arrived in Panama legally from the United States and stayed for 10 days, said Panama's security council chief, Ramiro Jarvis."
Isn't El Shukrijumah the one who is nicknamed Jafar the Pilot and thought to be the next Mohamed Atta?

"El Shukrijumah"
Good catch
