The bomb, which also left eight people injured, went off in an industrial part of the capital’s southern Bayaa neighborhood, Baghdad Police Captain Nazhan al-Khedr told Anadolu Agency.
No group has yet claimed responsibility for Tuesday’s deadly attack. In recent months, devastating bombings -- often featuring explosive-laden vehicles -- have become commonplace in Iraq’s violence-prone capital.
The Iraqi authorities typically blame such attacks, which frequently target civilian areas, on the Daesh terrorist group, which captured large swathes of territory in northern and western Iraq in 2014.
