Meanwhile, Jordanian authorities announced Saturday that raids earlier this month uncovered an Al Qaeda cell in Jordan that was planning to detonate a huge chemical bomb at the headquarters of the Jordanian Intelligence Services, the US Embassy, and other targets in Amman. They said the raw materials could have killed as many as 20,000 people in gas attacks.
''There is evidence that it came from Syria into Jordan," Engel said of the chemical materials and explosives. ''The Jordanians believe that and I believe that."
