 As the siege continued, insurgents continued to conduct hit-and-run attacks on U.S. Marine positions, despite the fact that U.S. Marines were under a unilateral ceasefire.It was also reported that the Marines wanted a cease-fire because they were not being resupplied, due to the insurgent capture of the main highway from Baghdad to Anbar.On May 1, 2004 U.S. forces withdrew completely from the city, and control of the city was turned over to the Fallujah Brigade (which was under control of a general who had served under Saddam Hussein).
