The 9/11 Commission Report: The Millennium Crisis

A phone call heard by Jordanian authorities, investigating extremists in the country, heard a call between Abu Zubaydah, a suspected Bin Laden associate at the Khalden training camp in Afghanistan and a Palestinian activist, Abu Hoshar. They heard what amounted to a very cryptic message of an incoming attack "the time for training is over".

When the Jordanian authorities arrested members of this plot, they found it entailed a multi-faceted operation which included, bombing the SAS Radisson hotel in Amman, attacking the border of Jordan and Israel as well as a bombing of an airport in the United States. Ahmed Ressam, an Algerian citizen, had trained in Khalden under Zubaydah, had independently taken it as his initiative to bomb Los Angeles International Airport.
