BBC: Clashes have flared outside Beirut as Lebanon's army struggled to contain the country's worst internal fighting since its bitter 15-year civil war.
While the capital seemed calm after four days of fighting killed 38 people, violence spread in hills to its east.
Earlier, troops had deployed in the northern city of Tripoli to end battles between Hezbollah sympathisers and supporters of the government.
Thousands fled their homes as running street battles raged overnight.
