On November 21, rioters, incited by false Iranian radio claims of an American attack on Islamic sites in Saudi Arabia, stormed U.S. Embassy Islamabad, trapping more than 130 people inside the communications vault for several hours. Several people died, including one young Marine Security Guard, Steve Crowley; the entire embassy was burned and eventually had to be rebuilt (with money from the Pakistani government).
Normally, communication with a country’s leader would be the most important step in assessing such a situation and attack on a foreign embassy. However, in this case, Pakistani President Zia al-Haq was unreachable, as he was out in the countryside riding a bike. The siege of the embassy grounds lasted for hours, as the army was delayed or simply was not ordered to rescue the American diplomats and staff trapped in the embassy’s vault.
