Lebanese state media says the army has captured a number of strategic hilltops from Islamic State group militants in the east of the country.

The National News Agency says the Army captured several hills between the frontier towns of Ras Baalbek and Arsal.

The report on Sunday comes two days after the politically influential leader of the militant group Hezbollah announced the Army would lead the fight against the militants in the border region. Hezbollah managed a campaign against al-Qaida-linked fighters also in the border region in July, leaving the Lebanese Army to take up positions behind the front lines.
