According to the WSJ ("Saudi Appointment Suggests Bigger Regional Ambitions") Saudi Arabië has appointed prince Bandar to head of the security service.
Prins Bandar was during many years ambassador in Washington and he was involved in the buildup of the Afghan resistenceafter 1979. Accroding to some sources he was involved in the "Arab Spring" in some countries, including Syria.
It looks likely that we can expect more activity from the Saudi secret service. Unfortunately that will mean more destabilization in other countries in the region.
This article (The Middle East counter-revolution) provides some background. Bandar is part of the Sudairy clan of the Saudi royal family. That clan is in a power struggle with some other parts of the family.
