Violations were committed by both major political parties, namely Fatah and Hamas. Although, the observers reported, Hamas had an advantage in mobilizing Palestinian facilities for its own political purposes."^[32] Violating the code of conduct, Hamas was able to use its militias and networks for propaganda and intimidation purposes, as well as heavily utilizing mosques for that purpose.^[33] A national monitoring committee set up by the Arab Thought Forum recorded reports of 242 violations in total throghout the election."
