Here's a YouTube link to Al-Jazeera's English coverage of the recent clashes in the Lebanese port city of Tripoli. Note that the fighting between the residents of the largely Alawite Baal Mohsen and the predominantly Sunni Beb al-Tabbaneh neighborhoods is reminiscent of the 1980's when, during the civil war, the same areas were respectively split between their support for the Syrian Army and Fatah.
Although the Lebanese Army moved in on Monday evening to help restore order, don't be surprised if things heat up again.
