A car bomb has exploded in a stronghold of the Lebanese Shi'ite militant group Hezbollah, wounding at least 37 people.
The blast Tuesday in Beir el-Abed, a southern suburb of the capital, Beirut, set several cars on fire and sent large plumes of smoke rising into the air. It hit a busy commercial and residential neighborhood that is also home to some Hezbollah offices.
There was no immediate claim of responsibility for the attack.
Lebanon has seen sectarian fighting tied to the civil war in neighboring Syria, with Shi'ites mostly siding with Syrian President Bashar al-Assad and Sunnis largely supporting opposition rebels.
Hezbollah fighters have gone into Syria to join Mr. Assad's forces.
Southern Beirut has been the scene of other explosions in recent months, including in May, when two rockets struck the area.
