(AP Photo/IntelCenter) (Newser) – Al-Qaeda became the latest terrorist organization to claim responsibility for the blast that killed eight operatives at a CIA base in Afghanistan last week, with a statement on the al-Qaeda website identifying the bomber as Abu Dujana, a prominent Islamist author and staple on jihadi websites, CNN reports. US intelligence says the bomber was a Jordanian doctor named Humam Khalil Abu-Mulal al-Balawi, a double agent who'd been working closely with the Jordanian agent killed in the attack. The seven CIA operatives killed in the blast included two contractors of the former Blackwater and two women, one of them the head of a Forward Operating Base in Khost Province, the New York Times reports. The Afghan and Pakistani wings of the Taliban, among other groups, have also claimed responsibility for the attack.
