The Syrian opposition on Sunday entreated the Arab League to adopt a tougher stance against Hezbollah’s intervention in the Syrian civil war and occupation of several border villages.

Syrian National Council leader George Sabra met Arab League Secretary-General Nabil al-Arabi in Cairo and raised his concern over Iran’s growing intervention in the fighting in Syria and Hezbollah’s taking over of villages on the Lebanon-Syria border.

The Lebanese news site al-Kalima Online reported last week that the Free Syrian Army accused Hezbollah of occupying six Syrian villages on the Lebanese border. The occupation of the villages, according to an FSA spokesperson, followed clashes between Hezbollah and FSA forces along the border.

The FSA on Thursday lashed out against what it said were Hezbollah hostilities and bombarded the group’s positions inside Lebanon for the first time. Earlier last week, Hezbollah and Syrian rebels clashed on the Lebanon-Syria border, leaving at least one Hezbollah fighter and five rebels dead.

Hostilities between the rebel group and the Iranian-backed Shi’ite militia continued unabated on Sunday, as the FSA reported three long-range missiles were fired into Syria from the Hezbollah-controlled areas of Lebanon.

Lebanese opposition MP Walid Jumblatt denounced Hezbollah and asserted on al-Jazeera that “Hezbollah is fighting inside Syria in support of the Syrian regime on orders from the Islamic Republic of Iran.”
