Lebanese government leader Saad Hariri, head of the Sunni Future Party, offered a truce on condition that Hezbollah put down its weapons and agree to elect a consensus candidate as Lebanon's next president. Hezbollah rejected the offer and by the end of Friday succeeded in taking control of most of western Beirut.
Fighters of Hariri's Future movement have now left the streets. A television and radio station tied to the movement were closed after the building was set ablaze.
The week's battles were a show of force reminiscent of Lebanon's 15-year civil war, during which armed militias from each religious community engaged in regular street fights.
Lebanon's 1975-90 civil war left 150,000 dead and much of the city devastated and carved into warring sectarian enclaves.
