Although President Abbas maintained control of the West Bank, terrorist organizations continued their activities in some areas there, while Hamas established de facto control over the Gaza Strip. President Abbas repeatedly called for an end to the violence against Israel and for a cessation of the internal violence between Fatah and Hamas, but these calls failed to prevent the numerous attacks that were launched.
The hostilities between Israel and the terrorist organizations in the Palestinian territories resulted in numerous casualties as well as damage to property. During operations in the West bank and in Gaza, the IDF killed 782 Palestinians and destroyed several citrus, olive and date groves, and irrigation systems. This number includes at least 315 casualties as a result of the airstrikes against Hamas facilities in Gaza during the first days of "Operation Cast Lead". It also includes targeted killing operations in which, according to the Israeli NGO, B'Tselem, Israeli forces targeted and killed 14 Palestinians — most were affiliated with terrorist organizations. Palestinians, on the other hand, killed 19 Israeli civilians and 10 IDF soldiers in the occupied territories.
During 2008, the IDF also conducted numerous incursions into the Palestinian territories in order to carry out arrest operations and to kill suspects of terrorist activity. Palestinians responded by firing on the Israeli forces and by booby trapping homes and apartment buildings. In response, the IDF raided and destroyed buildings in which militants were allegedly harbored. These actions often resulted in civilian casualties.
During the year, there was a significant increase in violent attacks by settlers against Palestinians. For example, on June 20 and July 21, settlers from the settlements of Yitzhar and Har Bracha launched several improvised rockets at nearby Palestinian villages.
Israel also conducted large scale arrests in the West Bank; however, most arrests targeted specific persons. According to the UN Office for the Coordination of Humanitarian Affairs (OCHA), there was a rise in the number of IDF search and arrest campaigns during the first 10 months of the year: the IDF arrested an average of 83 persons every week, and a total of 4,078 search and arrest campaigns were conducted in the West Bank as compared to 2,613 during the same period in 2007.
