Protests broke out in several Libyan cities, particularly in the second largest city of Benghazi, where demonstrators called for political and economic reforms in the country ruled by Muammar Gaddafi for more than 40 years.

Earlier reports said that live ammunition has been used by the Libyan security forces against the protesters, and at least two policemen were killed in the clashes.

Two of Libya's neighbors, Tunisia and Egypt, have seen their former leaders ousted from power following popular protests against the regime.
