Most wanted Iraqi terrorist Abu Musab al-Zarqawi was within minutes of capture by US forces on 20th February but managed to escape, leaving behind two associates, his laptop computer and approximately $104,000 in cash.
Intelligence had reported that al-Zarqawi was on the move and traveling towards the town of Ramadi. A checkpoint was set up and as a car was pulled over by troops operating with a covert military unit a pickup truck behind turned around and sped off.
By the time the pickup had been relocated and stopped, al-Zarqawi was gone, probably after jumping out as the truck went under an overpass. The U.S. military at least has recent pictures of the militant leader, recovered from his My Pictures folder.
