Gulf states are considering sanctions against Hezbollah.

This is a new sign that the civil war in Syria is increasingly destabilizing neighboring Lebanon.

On June 2nd, Syrian opposition groups and the Hezbollah armed group (in southern Lebanon, bordering Syria) engaged in fierce fighting inside Lebanese territory.

At least 21 Syrian opposition fighters and one Hezbollah member were killed in clashes in the town of Baalbek in the Bekaa Valley (Lebanon). Hezbollah, a Shiite Muslim movement in Lebanon that supports Syrian President Bashar al-Assad, is believed to be fighting alongside Syrian government forces against opposition groups in the Syrian border town of Qusair.

The Syrian opposition is threatening to attack Hezbollah bases in Lebanon in retaliation for Hezbollah's support of President Bashar al-Assad's army in attacking the town of Cuse.

Hezbollah's involvement in the Syrian war not only strained relations between Hezbollah and the Syrian opposition, but also sparked clashes in Lebanon between Sunni Muslims (who support the Syrian opposition) and Alawites (who support the Syrian president) on the evening of June 2nd in Tripoli (in northern Lebanon).

Clashes between the two communities have left at least 14 people injured. Earlier this week, the Lebanese parliament decided to postpone the general election scheduled for June due to the deteriorating security situation.
