Hezbollah guerrillas fought a deadly battle with Syrian rebels in Lebanon's eastern border region early on Sunday, security sources said, in the latest eruption of Syria's conflict on Lebanese soil. Lebanese security sources said at least 12 rebels were killed in the fighting east of the Bekaa Valley town of Baalbek, but the toll would not be clear until bodies were retrieved from the remote and rugged border area. One Hezbollah fighter also died, they said.
Syria's two-year-old conflict has increasingly sucked in its smaller neighbor, with fighting shaking the northern Lebanese city of Tripoli and rockets hitting the Bekaa Valley and southern Beirut. Shi'ite Muslim Hezbollah, which supports President Bashar al-Assad, is fighting alongside his army to drive rebels from the Syrian border town of Qusair, while Lebanese Sunni Muslim fighters have joined the anti-Assad revolt.
