Attacks in central and northern Iraq have killed at least 15 people and wounded about 35 others.
The attacks on May 28 come a day after more than 70 people were killed in a wave of bombings, mostly in Shi'ite areas of Baghdad.
The deadliest attack on May 28 was in Sadr City, a Shi'ite neighborhood of the capital.
Five people were killed and at least 26 were injured.
Iraq has experienced a surge in attacks since the beginning of the year, deepening concerns about a renewal of sectarian violence that killed thousands in 2006-2007.
Also on May 28, the Iraqi cabinet announced a series of measures aimed at stemming the violence, including "pursuing all kinds of militias."
The United Nations representative in Iraq, Martin Kobler, called on Iraq's leaders to engage in dialogue to end the violence.
