Fury at Libya's feuding leaders boiled over on Friday as protesters stormed the parliament building in the eastern city of Tobruk and staged the biggest demonstration for years in the capital Tripoli, in the west, Qazet.az reports.

With political factions squabbling over control of government after failing to hold a scheduled election last year, Libya has been thrust back towards territorial division and civil war as state services gradually collapse.

Protests over chronic power cuts brought demonstrators onto the streets of several cities, braving the wrath of armed factions to voice their anger at failures that have made life intolerable during the sweltering summer months.

In Tripoli's Martyrs' Square, several hundred people gathered to shout slogans demanding electricity, criticising armed factions and politicians and demanding elections in the capital's biggest protests against the ruling elite for years.
