Sa’dah insurgency
http://en.wikipedia.org/wiki/Sa’dah_insurgency

Belligerents:

Yemen, Saudi Arabia, Jordan, Morocco, Pakistan, United States, Al-Qaeda
vs.
Houthis, Iran, Hezbollah, Harakat al-Shabaab Mujahideen

What was happening here and since when are USA and Al-Qaeda allies?
Also I was reading that before 2001. Iran wanted to invade Afghanistan and overthrow Taliban but USA intervened and stopped Iran. Does anyone have any details?
