Cairo: Iraqi insurgent groups on Saturday warned Iraqis against cooperating with the Iraqi government following the death of Al Qaida leader Abu Musab Al Zarqawi.

Insurgent group Ansar Al Sunnah on Saturday posted a video on the internet showing militants interrogating and then beheading three Iraqis.

At the end of the tape, the group warned Iraqis against joining the security forces. "Otherwise, you will live in terror until we eliminate you and your fate will be in Hell," it said.

Insurgent groups also vowed to continue the fight, with the head of Al Qaida-linked Mujahedeen Shura Council calling for recruits.

"Iraq is the front defense line for Islam and Muslims, so don't fail to follow the path of the mujahedeen (holy warriors)," Al Baghdadi said.
