Syrian Rebels' Supply Lines

To expand its operations in Syria, the rebel Free Syrian Army (FSA) must secure supplies of weapons, food, water and other necessities. The most important supply lines for the rebels — though also the most difficult to maintain — come from Lebanon. The Syrian regime has a vast intelligence network in Lebanon to try to constrict this critical line of supply, but increasing activity across the Lebanese-Syrian border does not bode well for the Syrian regime's defenses at home or its position in Lebanon.
