BENGHAZI, Libya (AP) — Around 30,000 Libyans marched through the eastern city of Benghazi on Friday in an unprecedented protest to demand the disbanding of powerful militias in the wake of last week's attack that killed the U.S. ambassador and three other Americans.

Friday's march targeted in particular Ansar al-Shariah, a militia of Islamic extremists who officials and witnesses say participated in the consulate attack. The group is also accused of attacking Muslims who don't follow its harsh interpretation of Islam.
