One of the first Islamists to come to Albania was Muhammad al Zawahiri, (the brother of Ayman al Zawahiri, the leader of the Egyptian Islamic Jihad movement and Osama Bin Laden's key lieutenant) as an accountant for the International Islamic Relief Organization (IIRO). (Unbeknownst to Albanians, in addition to helping with relief and spreading correct Islam, IIRO was charged with the task of helping other members of Islamic Jihad find jobs within "charitable organizations building mosques, orphanages and clinics." By the mid-1980s, the Tirana cell of Islamic Jihad numbered 16 members, including a specialist in false identity documents, a recruit wanted on suspicion of involvement in the attempted assassination. This was later exposed during an investigation carried out by the American and Albanian secret services, In June 1998 three Egyptian Islamist accused of terrorist activities were arrested in Albania, with further arrests in September after the 1998 United States embassy bombings. )
