Insurgents signaled the fight is still on after Abu Musab al-Zarqawi’s death, posting an Internet video Saturday showing the beheading of three alleged Shiite death squad members in revenge for killing Sunnis.

It was the first known footage of beheadings to be posted by any insurgent group in months, and possibly timed to make clear to the U.S. and Iraqi governments that there will be no change in tactics even though al-Zarqawi is gone.

With its gruesome killings and militants chanting «Allahu Akbar», or «God is Great,» the 15-minute video illustrates the depth of Shiite-Sunni rivalries.

It shows three men in military uniform, sitting on the ground with their hands bound behind their backs in a small concrete room with gunmen standing around them.

Under questioning, the men say they are members of the «Wolf Brigade,» a special Iraqi police commando unit that Sunnis accuse of being a front for Shiite militiamen who kill Sunni Arabs.

Text in the video says the three were part of a «Shiite death squad» that kidnapped and killed Sunnis at checkpoints south of Baghdad in March and April. It says they were among 10 police commandos captured by Ansar al-Sunnah last month.

A militant off-camera asks them about the incident and other alleged slayings of Sunnis. The men reply in low voices, looking terrified. One mostly stares with his mouth hanging open.
