The US mission in Libya’s eastern city of Benghazi that came under attack in September was mainly a secret Central Intelligence Agency (CIA) operation, a report says. The Wall Street Journal said in a report on Friday that of the 30 US officials evacuated from Benghazi after the attack, only seven worked for the State Department, highlighting that the mission was mainly a CIA operation. 

The report added that the two security contractors who were killed in the incident -- former Navy SEALs Tyrone Woods and Glen Doherty -- were working for the CIA and not the State Department.
