Feud within key Yemen tribe could tear nation apart

The unrest shaking Yemen began months ago as part of the idealistic movement for democracy and political reform sweeping the Middle East. It is now a battle of money, power and egos within a single powerful clan that threatens to tear the country apart.
I don't know enough about Yemen to say whether it's true or not, but somhow the idea of an "idealistic movement for democracy and political reform" devolving into "a battle of money, power, and egos" seems fairly credible to me... though maybe I'm excessively cynical!
