Captain's Quarters has posted the translation of what appears to be an Iraqi Intelligence Services (Mukhabarat) document discussing the use of diplomatic privileges to carry out terrorist attacks.

The 2003 document (CMPC-2003-005745.pdf) mentions (among other terrorist and sabotaging techniques) using a briefcase bomb that can make it through a security check.

Use of diplomatic briefcases as an explosive device that can not be detected by an X ray device

The use of Iraqi embassies and diplomats to carry out attacks has been a tool of the former regime since at least the first Gulf war when many of their diplomats were ejected from their posts in various countries for attempting attacks. Their embassies also played a vital role in the attempted attacks on the Radio Free Europe building in Prague, the preparations for terror attacks in 98 during a near war with the Clinton administration and various attacks during the leadup to the current war.

These suitcase bombs may have been involved in the attempted IIS attacks in Yemen, Jordan and elsewhere during the leadup to the current war or may have been for other yet-to-discovered attempted attacks.
