More than 10,000 Libyans are marching through the eastern city of Benghazi, demanding the disbanding of powerful militias that run rampant in the city.

The giant march, which filled a major boulevard in the city of 1 million, is part of a new public backlash against militias sparked by last week's attack against the U.S. Consulate here that killed the ambassador and three other Americans. At least one militia is suspected of participating in the attack.

Multiple armed factions operate in Benghazi and other Libyan cities, boasting greater power than the weak government and security forces.

The crowd of men, women and children chanted, "No, no to militias" and carried signs and banners reading, "Where is the army? Where is the police?" and "Benghazi is in a trap."
