Iraqi security officials said on Monday that a suicide bomber targeted Shiite Muslims taking part in an annual pilgrimage in the northern Baghdad neighborhood of al Shaab.
The bomber killed nine people, four of whom were soldiers, and wounded 21 other civilians.
The attack targeted Shiite pilgrims during the lead-up to the religious commemoration known as Arbaeen, when Shiite faithful converge on the holy city of Karbala.
Arbaeen means the passing of 40 days after the anniversary of the death of Imam Hussein, the grandson of the Prophet Muhammad, who was killed in Karbala in the seventh century.
Many pilgrims are traveling on foot to the annual commemoration in Karbala. Despite tight security measures, the procession is often exposed to violence.
17 million pilgrims are expected to visit Karbala this year.
No one has claimed responsibility for the deadly attack, but the DAESH terrorist group is believed to be behind it.
Iraqi military announced on Iraqi state TV on Monday that civilians should leave Ramadi, the capital of Anbar province, which is located 115 kilometers west of Baghdad and has been under DAESH’s control since May.
The US-led Combined Joint Task Force, (CJTF) under Operation Inherent Resolve conducted seven air strikes near Ramadi on Saturday which targeted DAESH fighters, positions and weapons caches.
