Beirut, Reuters, 7 August 2017 – ISIS may have fired seven Grad rockets into Lebanon on Monday from its enclave on the border with Syria, without causing any injuries, a Lebanese security source said.

It would mark the first use of those weapons by ISIS fighters there for several years, and comes as the Lebanese army prepares for an expected assault on their enclave.

The rockets fell around the town of al-Qaa and led the Lebanese army to shell ISIS positions in the hills nearby, the source said.

The extremist militants and the Lebanese army have exchanged frequent shell, mortar and small arms fire over several years.
