A security source, speaking on condition of anonymity, said Hezbollah resistance fighters launched a barrage of rockets and mortar shells at Daesh positions on the outskirts of the village of Ras Baalbek, located 124 kilometers (77 miles) northeast of the capital, Beirut, on Friday, leaving five extremists dead, Lebanon-based Arabic-language al-Manar satellite television network reported.

The report comes as Daesh extremists and al-Qaeda-affiliated Nusra Front militants regularly infiltrate Lebanon’s border with crisis-hit Syria, clashing with both Hezbollah fighters and the Lebanese army soldiers.

On June 19, two Daesh commanders and seven other militants were killed during two separate Hezbollah operations.

A militant commander, identified as Abu Aisha al-Libi, and six of his comrades were killed, when Hezbollah fighters targeted a militant hideout on the outskirts of Arsal town, which lies about 124 kilometers (77 miles) northeast of Beirut.

Hezbollah fighters killed another Daesh commander, identified as Abu Akrama al-Zohouri, and another militant identified as Ahmad Abed al-Mohsen, during a separate offensive in the same area.

Takfiri militants have infiltrated into Lebanon from neighboring Syria. The foreign-sponsored conflict in Syria, which flared in March 2011, has claimed the lives of more than 250,000 people and left over one million injured, according to the United Nations.

Hezbollah resistance fighters have been helping the Syrian forces fighting against Takfiri militants on the Syrian soil near the border with Lebanon.
