The White House has publicly thanked the Saudi intelligence service for its cooperation
but the weeks of intelligence sharing with the Saudis that allowed the US to know in advance that parcel bombs were coming has not previously been reported.
US intelligence officials feared that al Qaeda terrorists in Yemen were plotting to attack the United States and actually intercepted what they now believe were "dry run" shipments to Chicago in mid-September, according to several people briefed on the plot and a senior US official. The senior US official told ABC News that the "dry run" involved a carton of household goods including books, religious literature, and a computer disk, but no explosives, shipped from Yemen to an address in Chicago by "someone with ties to al Qaeda in the Arabian Peninsula." Two bombs shipped by air from Yemen were intercepted in Dubai and the U.K. last week.
