TRIPOLI, Lebanon -- In this northern Lebanese city, two adjoining neighborhoods reflect the growing concern that the violence raging in Syria could soon spill into Lebanon, whose own sectarian civil war captivated the world a generation ago.
On the one side are the men of Bab al-Tabbaneh, a Sunni Muslim area that openly embraces the Free Syrian Army, the band of military defectors that has taken up arms against Syrian President Bashar Assad.
On the other are the men of Jebel Mohsen, an enclave that is predominantly Alawite, the Shiite Muslim sect to which Assad and much of his inner circle belong.
For two days last week, fighting shook the two neighborhoods, leaving three civilians dead and two dozen wounded, including members of the Lebanese army, which was deployed Sunday to separate the antagonists. But while calm has been restored, tensions remain high, and neither side expects the peace to hold.
