Lebanon's state news agency says that supporters of rival factions have clashed in a coastal town south of Beirut, leaving several people wounded.

The agency says the clash early Wednesday in the town of Saadiyat was between supports of the Sunni Future Movement and the Resistance Brigades, which is close to the Shiite Hezbollah group.

Sectarian tensions have increased in Lebanon since the start of Syria's crisis four years ago. The civil war has spilled over to Lebanon in the past, killing and wounding dozens.

A Lebanese security official said seven people were wounded. The official spoke on condition of anonymity because he was not authorized to brief the media.

The Lebanese army said one soldier was lightly wounded in the shooting, adding that troops are patrolling the area.
