Two bombs in a Sunni-majority area of west Baghdad killed at least 14 people on Friday, Iraqi medical officials said, the latest in a series of attacks targeting Sunnis.
The two roadside bombs also wounded at least 35 people, the officials said.
Other attacks targeting Sunnis, including two bombs near a mosque and one at a funeral procession, killed a further 51 people on Friday, after two days of attacks targeting Iraqi Shiites in which dozens died.
The violence raises the spectre of tit-for-tat killings common during the height of sectarian bloodletting in Iraq that killed tens of thousands of people, and comes at a time of simmering tension between the country's Sunni minority and Shiite majority.
With the latest attacks, more than 250 people have been killed in violence so far in May, according to AFP figures based on security and medical sources.
Violence in Iraq has fallen from its peak during the height of the sectarian violence, but attacks are still common, with more than 200 people killed in each of the first five months of this year, according to AFP figures.
