AP sources: Bomber at CIA base was a double agent

The suicide bomber who killed eight people inside a CIA base in Afghanistan claimed to have information about Osama bin Laden's second-in-command, and was being recruited as a double agent to infiltrate al-Qaeda, a former senior US intelligence official and a foreign government official confirmed Monday.

The bombing killed seven CIA employees - four officers and three contracted security guards - and a Jordanian intelligence officer, Ali bin Zaid, according to a second former US intelligence official. (AP)
