The raise of Al Qeada

After his expulsion from Saudi Arabia, bin Laden established headquarters for al-Qaeda in Khartoum, Sudan. The first actions of al-Qaeda against American interests were attacks on U.S. servicemen in Somalia. A string of terrorist actions suspected to have been orchestrated by al-Qaeda followed. And in August 1996 bin Laden issued a "Declaration of War" against the U.S. Al-Qaeda also worked to forge alliances with other radical groups. In February 1998, bin Laden announced an alliance of terrorist organizations—the "International Islamic Front for Jihad Against the Jews and Crusaders"—that included the Egyptian al-Gama'at al-Islamiyya, the Egyptian Islamic Jihad, the Harakat ul-Ansar, and other groups.
