A booby-trapped car, filled with around 50 kg of explosives, went off in the Bir el Abd area of the Lebanon capital, Xinhua reported citing a security source.
A TV channel footage showed burning cars and plume of black smoke over the blast scene. Media reports said a number of families were still trapped inside some burning buildings in the area.
Hezbollah's Al-Manar TV said: "The remains found 10 metres away from the scene of the deadly blast might be the suicide bomber."
A group dubbed the Brigades of Aisha Umm al-Moemeneen claimed responsibility for the bombing in an online video later and threatened to launch further attacks.
On July 9, a booby-trapped car exploded at a parking lot in Bir al-Abed area in Beirut, leaving 53 people wounded and causing heavy material damage.
In May, two rockets hit Beirut's southern suburb of Shiyyah, wounding four people.
