Lebanese security officials say Hezbollah fighters have exchanged fire with residents of the eastern city of Baalbek in clashes that left two militants dead.
The officials say the shooting occurred Saturday at a Hezbollah checkpoint in the city, a stronghold of the militant group.
The officials, who spoke on condition of anonymity in lines with regulations, said two Hezbollah militants were killed and two members of the Shiah family were wounded.
Lebanon's state-run National News Agency said three people died. It wasn't immediately possible to reconcile the death tolls.
Hezbollah set up checkpoints in its strongholds after an Aug. 15 blast in Beirut's southern suburbs killed 27 people. Many resent the checkpoints.
The officials said Lebanese troops were trying to enter the area to separate the gunmen.
