Police and hospital sources say at least 22 people were killed in explosions across Iraq on April 26, including a suicide car bomb attack on a military post in western Anbar Province.
The sources said the deadliest attack came when a car packed with explosives was detonated at an army checkpoint near the town of Al-Nukhaib, killing at least seven soldiers.
Another six people were killed and 17 others wounded when a car bomb went off near Khilani Square in central Baghdad.
Six more people were killed in bomb attacks in Baghdad's predominantly Shi'ite districts of Amil, Hussainiya, and Bayaa. A car bomb killed three people and wounded seven in the town of Mahmudiya, about 30 kilometers south of Baghdad.
Government forces are also struggling to dislodge Islamic State militants from the western province of Anbar and much of northern Iraq.
In the town of Baghdadi, the Iraqi military says it has repelled an IS attack, killing 14 militants.
