The CIA conducts lethal drone strikes against al-Qaeda militants inside Yemen from a remote base in Saudi Arabia, including the strike that killed the US-born al-Qaida operative Anwar al-Awlaki.
The location of the base was first disclosed by The New York Times online yesterday night.
The officials spoke on condition of anonymity because portions of the military and CIA missions in Yemen are classified.
Any operation by US military or intelligence officials inside Saudi Arabia is politically and religiously sensitive.
Al-Qaeda and other militant groups have used the Gulf Kingdom’s close working relationship with US counterterrorism officials to stir internal dissent against the Saudi regime.
