Ain el-Hilweh Camp Rocked by Grenade

NNA said the incident in the camp's al-Ras al-Ahmar neighborhood did not cause any casualties.

The camp has been the scene of numerous armed clashes in recent years.

By long-standing convention, the Lebanese Army does not enter Palestinian refugee camps, where security is managed by joint committees of Palestinian factions.

Ain el-Hilweh is an impoverished, overcrowded camp near the coastal city of Sidon, and is home to some 61,000 Palestinians, including 6,000 who have fled the war in Syria.
