I'm not sure how accurate this is and it's just a rumor at this point. It has been reported by several sources that Abu Musab al-Zarqawi has been captured.

Itar-Tass

Abu Mus'ab al-Zarqawi, whom the US occupation authorities declared to be the "target number one" in Iraq, has been arrested in the city of Baakuba, the Emirate newspaper al-Bayane reported on Tuesday referring to Kurdish sources. Al-Zarqawi, leader of the terrorist group Al-Tawhid Wa'al-Jihad, was recently appointed the director of the Al-Qaeda organisation in Iraq.

The newspaper's correspondent in Baghdad points out that a report on the seizure of the terrorist, on whom the US put a bounty of 10 million dollars, was also reported by Iraqi Kurdistan radio, which at one time had been the first to announce the arrest of Saddam Hussein.
