Zawahiri, whose EIJ is said to have merged with al-Qaeda in 1998, is also believed to have been one of the masterminds of the suicide bombing of the USS Cole off the coast of Yemen in 2000, and the "brains" behind the September 11th attacks on the United States.
Zawahiri, čiji se EIJ navodno spojio s al-Qaedom 1998. godine, također je, kako se vjeruje, jedan od glavnih planera samoubilačkog bombaškog napada na američki razarač USS Cole kod obale Jemena 2000. godine i "mozak" iza napada 11. rujna na Sjedinjene Američke Države.
