Clashes rock Tripoli and Beirut

Syria's civil war is fuelling clashes between Sunni Muslims and Alawites in the northern Lebanese city of Tripoli.

On Monday, four people died as gunmen traded fire on the streets, prompting concers that Lebanon could see a new era of violence.

Sporadic fighting has also spread to the capital, despite a heavy military presence across much of Beirut.

Prime Minister Najib Mikati and President Michel Suleiman met to discuss the emerging crisis, but did not speak to the media afterward.

However, authorities did say they'll stamp out unrest and "take decisive measures" to prevent Lebanon from slipping into a second civil war.

Tensions are rising in the wake of the assassination of a senior Syrian intelligence officer and seven others in Beirut on Friday.
