Attack in area full of used car dealers is the latest in renewed wave of mostly suicide blasts to strike Iraqi capital, Al Jazeera reported.
A car packed with explosives has blown up in the south of Baghdad, killing at least 55 people and wounding dozens more.
The Islamic State of Iraq and the Levant (ISIL) claimed responsibility for Thursday's attack that came amid a renewed wave of violence in the Iraqi capital.
Security sources said the vehicle which blew up was parked in a crowded street full of garages and used car dealers, in Hayy al-Shurta in the southwest of the city.
Medical sources confirmed the death toll to Al Jazeera.
