I have read reports that identify the three compounds as being Al-Hamra, Jadawel, and Cordoval. I don't remember a Cordoval compound, so I strongly suspect that this was actually Cordoba, which was my old compound. That would make sense, since all three compounds are in the same general area, and all three are on the A list of good compounds. We have been to all three compounds, and have or had friends at all of them.
Most of these compounds are a mix of Europeans, Americans, and people from Middle Eastern countries, such as Lebanon and Jordan. My compound never had a huge number of Yanks, it was mostly Europeans. Many of the Americans were, in the words of our racist compound manager, "plastic Americans", i.e., naturalized citizens. Our remaining close friends at Cordoba are Canadian, Irish and British.
The most serious damage appears to have been at Al-Hamra, and, in the past, there were a lot of Americans living there. Of course, the nationality of terror victims shouldn't matter, but it will get more coverage if there were westerners and/or Americans injured. I read that there was shooting within Al-Hamra before the explosion, and that there were many injuries, and possibly some fatalities.
I hate being right. All of the people that thought we were being paranoid for leaving probably wish they'd left as well.
