Americans were stunned on October 11 when the Justice Department unsealed its complaint against Mansour Arbabsiar, a 56-year-old used-car dealer from Corpus Christi now in federal custody, and Ali Gholam Shakuri, a member of the Iranian Revolutionary Guard Corps-Quds Force. Shakuri remains inside Iran. The pair have been charged with conspiring to kill the Saudi ambassador in Washington, Adel Al-Jubeir.

As disclosed by the Treasury Department, the plot was coordinated by Arbabsiar’s cousin, Abdul Reza Shahlai, a top Quds Force functionary whom the Treasury designated in 2008 as one of several “individuals and entities fueling violence in Iraq.” Shahlai was described then as the planner of “special group attacks” by the Mahdi Army, headed by Moktada Al-Sadr, against Coalition forces on the territory of Iran’s western neighbor.
