A bomb exploded under a car in the south Beirut suburb of Hay al-Selloum late Monday night, the Now Lebanon website reported.
There were no casualties and gunfire was heard in the area after the explosion, the report said.
LBC television reported that the explosion targeted a Honda belonging to a man identified as Abbas Mazloum, adding he was not affiliated with any Lebanese political party. Earlier reports said that Mazloum was a member of the Lebanon-based Hizbullah terror group.
LBC also reported said that Hizbullah security was deployed to the site of the explosion along with army units.
Hay al-Selloum is a predominantly Shiite neighborhood within the Hezbollah stronghold of Dahiyeh.
Hizbullah’s Al-Manar TV reported that a small explosion hit the area and did not cause any injuries.
Meanwhile, an anonymous security source told AFP that that “a bomb exploded under a car in Hay al-Selloum, causing only material damage.”
Al-Jadeed TV, another Lebanese television network, reported that the bomb was small in size and only resulted in material damage, but it detonated in a crowded area.
Such explosions occur from time to time in Lebanon, usually targeting Hizbullah bases or weapons depots.
Last month, a huge explosion hit a Hizbullah weapons depot near the border with Israel. Hizbullah immediately accused Israel of carrying out an aerial bombing.
In October, explosions at a Hizbullah weapons cache in the Bekaa Valley in eastern Lebanon killed nine people, among them members of the terror group.
