Report: Yemen-based al Qaeda members involved in Benghazi attack

Last year’s attack on Sept. 11 in Benghazi left four Americans dead, including U.S. Ambassador Chris Stevens.

The Benghazi attack has been previously linked to al Qaeda in the Islamic Maghreb (AQIM), an offshoot of al Qaeda based in Northern Africa. AQAP is the al Qaeda-affiliated group based in Yemen and is generally considered the most dangerous affiliate.

If the Benghazi attack was, in fact, planned in advance by AQAP members, it could indicate further cooperation than previously realized between al Qaeda affiliates.

The FBI released photos Wednesday of three men it was looking for who were on the grounds of the U.S. facility the night of the attack. The agency did not say whether they were suspected to have participated.
