Seven rockets fired by the jihadist Islamic State group on Monday landed in and around the eastern border town of al-Qaa, causing no casualties, media reports said.

“Four rockets fired by the IS group landed near a Lebanese army post inside the town of al-Qaa as three others hit its peripheries, causing no casualties,” TV networks quoted security sources as saying.

The army retaliated by firing artillery and multiple rocket launchers at the group's posts in the outskirts of al-Qaa and Ras Baalbek, achieving direct hits, LBCI television reported.

Earlier in the day, the National News Agency said the army was targeting with intense shelling the group's posts in the outskirts of al-Qaa and the neighboring towns of Ras Baalbek and al-Fakiha.

The army has intensified its shelling of IS’ posts in recent days amid reports that a military operation to oust the jihadist group from the border region has become imminent.

The developments follow a Hizbullah offensive that ended the presence of the jihadist al-Nusra Front group in the outskirts of the northeastern border town of Arsal.
