Syrian civil war spillover in Lebanon Fighting from the Syrian civil war has spilled over into Lebanon as Lebanese opponents and supporters of the Syrian government have traveled to Syria to fight , and attacked each other on Lebanese soil . The Syrian conflict has been described as having stoked a " resurgence of sectarian violence in Lebanon " , with Lebanon ' s Sunni Muslims mostly supporting the rebels in Syria , while Shi ' ites have largely supported Assad , whose Alawite minority is usually described as an offshoot of Shi ' a Islam .

The March 14 alliance , led by the mainly Sunni Muslim Future Movement , which is allied with the Maronite Christian Kataeb Party , has called for Lebanese aid to the Free Syrian Army and taking a stronger stance against the Syrian government .

Sakr later claimed the tapes were edited , and that he only provided Syrians with milk and blankets . Sunni extremists from Tripoli have been flocking to Syria to join the terrorist al - Nusra Front .
