A car bomb exploded in an industrial area of south Baghdad on Tuesday, killing at least four people, Iraqi police said.
"The blast was caused by a parked car bomb in an industrial area," home to many car maintenance workshops and companies in Bayaa, a neighbourhood with a mixed Sunni and Shia population, a police colonel said.
He said at least four people were killed and 14 wounded, a casualty toll confirmed by hospital sources.
The Iraqi capital was rocked by a wave of deadly suicide bombings during the first days of 2017 but relatively few explosions have been reported since.
There was no immediate claim of responsibility for the blast in Bayaa.
Nearly all suicide attacks are claimed by the Islamic State (IS) militant group, which is currently defending its last major Iraqi bastion of Mosul against a massive, four-month-old operation by the security forces.
