Here is the article at Debka about it, with this interesting addition:
"DEBKAfile’s terrorism experts add: These reports have spurred Washington’s efforts to lay hands on al Qaeda’s biological weapons expert, the Jordanian terrorist Abu Musab Zarqawi who received medical treatment in Baghdad during his flight from Afghanistan and trained with Saddam Hussein’s intelligence officers in the use of biological and chemical weapons at an Ansar al Islam facility in northern Iraq.
At present, Zarqawi is in Iran under Iranian Revolutionary Guards protection. Jordanian king Abdullah will be traveling to Tehran in the next few days. He will make a second effort to persuade the Iranians to surrender Zarqawi, who is under sentence of death in the kingdom for his role in the failed Millennium Plot against Western targets in Amman. Earlier this year, the monarch requested his extradition from Tehran in vain."
