The death of US ambassador Christopher Stevens in a military-style attack on the US consulate in Benghazi was linked, without evidence, to Libya's largest Islamist brigade, Ansar al-Sharia.
In an exclusive interview with the BBC, commander Mohammad Ali al-Zahawi denied any involvement in that and other attacks against Western targets but said it rejected what it saw as the imposition of democracy in Libya.
