evidence: Since the beginning of the Syrian conflict nearly three years ago, Lebanon’s Arsal, a lone enclave in the eastern Bekaa Valley for Sunnis sympathetic to the Syrian uprising, has served as a crucial logistical support network in the struggle against the Assad regime. Located in the northeastern corner of Lebanon on the border with Syria, the town lies nearly equidistant from Hezbollah’s Bekaa Valley strongholds of Baalbek and Hermel. In spite of its isolated position, the geostrategic relevance of Arsal lies in its close proximity across the border from the contested Qalamoun mountain range. Qalamoun is an opposition stronghold in western Syria between Homs and Damascus that is currently the site of an intense battle for control of key supply lines along the M5 highway. Lebanese authorities have long neglected Arsal and the notoriously porous nature of the border region has made it a hub for smuggling people, weapons, and drugs across the border into Syria. The smuggling routes through the connecting mountains flow freely in both directions, as weapons and fighters flow from Arsal into Qalamoun while car bombs and refugees flow in the opposite direction. Since the start of the Syrian conflict, Arsal’s pre-war population of 40,000 has more than doubled as 60,000 Syrian refugees have fled to the town due to the nearby fighting, according to municipality figures.
