In 2003 and 2004, Hezbollah was the most prominent cause of terror in the territories: The Israel Defense Forces estimates that more than 70 percent of the terror attacks in the West Bank were initiated by the Lebanese group, which provided funding and general instructions for the attacks, most of which were carried out by Fatah and Islamic Jihad...
