At the beginning of August 2014 clashes broke out in the Lebanese town of Ersal between armed factions fighting in Syria, among them jihadist groups such as ISIL and the Nusra Front, and the Lebanese army. These clashes continued for five days and ended with the withdrawal of the Syrian fighters from the town as part of an initiative under the auspices of the Association of Muslim Ulema in Lebanon and the Lebanese Institute for Democracy and Human Rights (LIFE). In view of the contradictory accounts and the mutual recriminations, this paper looks at what really happened in Ersal, the background that led the crisis to develop, the positions and calculations of the various sides, and the repercussions in Syria and Lebanon.
