A suicide bomb blast occurred on Monday night during a Shiite Muslim procession, an annual ritual to commemorate the martyrdom of Prophet Mohammed’s grandson Hussein, in Shaab, a northern Baghdad neighbourhood leaving seven dead - including two police officers – and wounding 23 others.
As Shiite Muslims celebrate the holy day of Ashura over the weekend, several small number of attacks have been reported in Iraq.
ISIS, who has captured parts of western and northern Irag last year, claimed responsibility over the explosion in a statement published online by a group of supporters.
According to unconfirmed reports, the group said that the target was “rejectionists,” an offensive term used towards Shiite Muslims. They claimed 20 people were killed and 40 injured.
An Interior Ministry spokesman noted that the blast was conducted by an attacker wearing an explosive waistcoat.
Iraq has been exposed to attacks between Shiites and Sunnis, ignited by the rise of Sunni rebellions of ISIS.
Security has improved over during the Ashura commencement in recent years, since attacks by suspected Al Qaeda suicide militants killed 171 people during Ashura rituals in Kerbela and Baghdad in 2004. Attacks have been ongoing since then.
