Great pics, totally going to blow mine out of the water when I finish my trip report (that's been delayed due to holidays) to Yemen. My crappy little point and shoot won't match yours.
Personally, I loved the Old City and Wadi Dhar, but my twinged a bit when I looked at my pics vs. those from the BBC about the attack on the defense ministry yesterday and saw I had the same things in my album. I'm not sure about you though, but I didn't feel unsafe at all.
