The heavily fortified US consulate in Jeddah, Saudi Arabia was attacked on December 6th, 2004. Four Saudi Security guards and five non-US staff members were killed and several US staff members were injured. Three of the attackers were killed and two captured. In response, the US embassy and consulates were closed for the day throughout the Kingdom. The US has already sent home non-essential staff and has urged tens of thousands of American corporate employees to leave the country.
As anticipated by this author, the global guerrilla campaign in Saudi Arabia is in motion. The insurgent "chatter" in the country has been at a minimum since this summer, which presaged new violence this winter (and not that the Saudi counter-terrorist operations were successful). The attack on the US consulate is part of a psychological "shaping" operation by global guerrilla groups in the country. It is important for the guerrillas to frame this conflict in terms of a war against the US and the Saudi Royal family (the "apostate kleptocrats") prior to full-scale systems disruption (think in terms of methods that route around the highly optimized tolerance of current Saudi systems).
