Al-Manar TV station said party fighters shelled ISIS positions on the outskirts of Ras Baalbek in an area it identified as Shanshara.

Hezbollah has been targeting ISIS positions on Ras Baalbek's outskirts for at least three consecutive days.

The party has intensified its attacks on ISIS east of Ras Baalbek after it repelled a militant attack last week, which sparked a battle that killed 50 ISIS militants. It was the most serious border confrontation between the two sides since early last month.

On Tuesday, Al-Manar said that ISIS's "emir" for the Qalamoun region Abu Balqis al-Baghdadi was killed in shelling on the eastern outskirts of Lebanon's Arsal, about 7 kilometers south of Ras Baalbek, in the area of Wadi Hmayed.

Hezbollah and the Syrian army have been battling ISIS and Nusra Front fighters in the Qalamoun region along Lebanon's eastern border with Syria since early last month.

Nusra and ISIS Terrorists

The allied forces have captured about two-thirds of the rugged border region from the terrorists since launching the offensive on May 4. Militants are now mostly holed up in northern Qalamoun, on the eastern outskirts of Arsal and Ras Baalbek.

Hezbollah chief Seyyed Hasan Nasrallah vowed last week to oust ISIS from northeastern Lebanon.
