The death toll from the suicide attack carried out Sunday in the Shiite-majority city of al-Kazemiya, north of Baghdad, has risen to 21 people, with 35 others wounded, a source from the Iraqi police told EFE.

The source said that the bomber blew himself up early in the morning in Aden Square with an explosive belt that was attached to his body.

The explosion also caused damage to several vehicles and nearby buildings.

Security forces surrounded the area of the attack and transferred the wounded to a hospital in al-Kazemiya, near the scene of the attack, the source added.

Baghdad has been in a state of alert since the attack perpetrated by the Islamic State terrorist group on the Shiite-majority al-Karrada city on July 3, which killed at least 292 people and wounded 223 others.
