WASHINGTON, DC The Obama administration for the first time is identifying specific groups as being involved in the attack in Benghazi, Libya, that killed Ambassador Chris Stevens and three other Americans.
The State Department is issuing terrorist designations for three militants and three extremist groups, including two it says were involved in the 2012 attack.
The department is designating the Darnah and Benghazi branches of Ansar al-Sharia in Libya and a third branch in Tunisia as foreign terrorist organizations.
It also designated militants including Sufian bin Qumu, leader of the Darnah branch released from Guantanamo Bay in 2007. He and two others are specially designated as global terrorists, barring anyone from supporting them.
