A car bomb killed at least 16 people and wounded 30 Wednesday in a mostly Shiite Muslim neighbourhood of the Iraqi capital, a police colonel said.
The attack, which struck a busy commercial street in the western district of Bayaa, was the latest of a number of particularly deadly incidents in Baghdad in less than a week.
On Tuesday, at least 30 people died in two car bombings and attacks on police.
The worst car bombing left 19 dead and 43 wounded in the eastern district of Baghdad al-Jadida, a predominantly Shiite area that has been one of the most targeted by car bombs in recent years.
Another four people were killed and 10 wounded in a similar attack in the southern neighbourhood of Zafaraniya.
The Islamic State group claimed responsibility for both attacks, saying they had targeted Shiite militiamen, a claim it often makes even when most of the victims are civilians.
On Friday, a huge suicide car bomb attack claimed by IS killed dozens of people in Khan Bani Saad, a town just north of Baghdad.
