At least 20 people, including a suicide bomber, were killed Wednesday in a series of attacks in Iraq, said police.
Forty were reported wounded.
The deadliest attack was in Baquba, north-east of the capital Baghdad, where a suicide bomber blew himself up at a mourning ceremony, killing at least 11 others and injuring 15, dpa reported.
Meanwhile, eight were killed and 25 wounded in three car bombings in northern and central Baghdad, said police.
Attacks, mostly blamed on Sunni militants, are almost daily occurrences in Iraq.
In December, militants of the Islamic State in Iraq and the Levant (ISIL) took control of the city of Fallujah, as well as vast areas in Ramadi, the capital of the Sunni-dominate western province of Anbar.
Sectarian tensions arose in Anbar after troops loyal to the Shiite-led government cleared out a Sunni protest camp in Ramadi.
The violence in Anbar has raised the prospect of a return to the sectarian bloodshed that pushed Iraq to the brink of civil war in 2006 and 2007.
According to UN estimates, 8,868 people were killed in 2013, the highest annual death toll in five years.
