BEIRUT - A suicide bombing in a southern Beirut neighborhood killed a security officer and wounded 20 people, officials said Tuesday, as an al-Qaeda-linked group warned that such attacks will continue as long as the militant Hezbollah group is taking part in Syria's civil war.
The overnight attack -- the second such bombing this week - heightened fears that Lebanon was reverting to a cycle of violence after a few months of respite.
The explosion occurred near a checkpoint and a cafe in the Shatila area of the Lebanese capital just after midnight Tuesday. (AP)
