A Lebanese security official confirms an explosion has taken place in a predominantly Shiite suburb south of Lebanon’s capital, Beirut.
The official says said the blast was heard near a security office in the suburb of Burj al-Barajneh.
The official says the nature of the explosion was not immediately clear, although other reports indicate it may have been a suicide bombing.
The southern suburb of Beirut is a stronghold of the militant Hezbollah group and has been hit by several bombings in the past that have killed dozens.
