Any names stand out?
For me it was Faris Muhammad Man'a, a prominent shaykh from Sa'dah and arms trader - although he has many other business interests - and the brother of the former governor of Sa'dah. Faris is incredibly well-connected, or at least he was well-connected and not just in Yemen. He also used to have extensive holdings in the US, so there may still be a great deal for the US to go after.
Still it is interesting to see the US go after him not for his role in a particular incident in Saudi Arabia, but rather for his role in Somalia. Hmmm.
