A former senior intelligence official says the double agent who killed seven CIA employees last week had provided information that led the CIA to kill a number of al-Qaida leaders.
The former official says Humam Khalil Abu-Mulal al-Balawi had provided high-quality intelligence that established his credibility with Jordanian and U.S. intelligence.
The former official says that information led to drone-launched missiles strikes. CBS News first reported al-Balawi's connection to the missile strikes.
The attack at a CIA post in Afghanistan came after al-Balawi claimed he had information on Osama bin Laden's top deputy.
The former official was not authorized to discuss the matter and spoke on condition of anonymity.
