The Lebanese army's artillery was on Sunday (June 4th) pounding militant posts on the outskirts of the eastern border towns of Arsal and Ras Baalbek, Naharnet reported.
The operation came one day after an "Islamic State of Iraq and Syria" (ISIS) suicide bomber blew himself up outside a post belonging to rival group al-Nusra Front (ANF), now known as Fatah al-Sham Front, the National News Agency reported.
"A member of the attacking force blew himself up outside one of the posts" in the Ajram area in Arsal's outskirts, security sources said.
"The army's artillery targeted an ISIS infantry force that was trying to infiltrate into the Ajram area, inflicting confirmed casualties," the sources said.
