Iraqi police say at least 28 people have been killed in a series of explosions that tore through mainly Shi'ite areas of the country Sunday.
The deadliest attacks struck central and south Iraq late Sunday, including in the southern oil hub of Basra, where eight people were killed and at least 15 wounded in a car bombing.
Other attacks took place in Kut, Nasiriyah and the Shi'ite holy city of Karbala.
The blasts went off shortly before the evening iftar meal that ends the daylong fast during the Muslim holy month of Ramadan.
There was no immediate claim of responsibility for the attacks. But analysts say Sunni insurgents upset with Iraq's Shi'ite-led government have led a spike in unrest.
In recent days, at least 90 people have died in violence in Iraq between Shi'ites and minority Sunnis.
Iraqi Sunnis complain the Shi'ite-led government ignores their needs and is marginalizing them politically.
