Scores of troops and policemen are scouring the perimeter around the Lebanese presidential palace after two rockets hit the area overnight.
A Lebanese army statement on Friday said one of the rockets struck the front yard of a private villa while the other hit in Yarzeh district near the palace.
The attack late Thursday was the latest in a series of rocket attacks that targeted areas south of Beirut in the past two months as a fallout from Syria’s civil war.
Lebanon is deeply divided along sectarian lines and among supporters and opponents of Syrian President Bashar Assad.
Earlier on Thursday, Lebanese President Michel Suleiman gave a speech criticizing the involvement of the militant Lebanese Hezbollah group in Syria’s conflict in support of Assad’s forces.
