A suicide bomber killed himself and one other person when he detonated explosives in a van in southern Beirut on Monday, a Lebanese security source said. State news agency reported at least six wounded.
Lebanese television footage showed the chassis of a vehicle with no roof. Smoke rose in the air and debris lay on a street. Body parts, including a head, were on the road.
The target of the attack was not immediately clear. The van exploded on a highway in Choueifat, in the south of the capital. Choueifat is traditionally a Druze neighborhood, but is adjacent to a Shiite area.
A bystander said the minibus had been heading in the direction of those areas, which suggested the detonation may have been premature. It was not immediately clear if the bomber had been a passenger or the driver of the vehicle.
A man working at a petrol station near the site of the blast said: "There was glass everywhere. We saw a head. Then the legs landed near the station."
Lebanon is reeling from the fallout of Syria's civil war next door, and has seen its own share of violence in recent months. Hezbollah has sent fighters to support Syrian President Bashar Assad against majority Sunni Muslim rebels.
