Three Shiite Muslim pilgrims were killed by a roadside bomb as they walked to a holy site near the northeastern Iraqi city of Khanaqin on Tuesday, police said.
ISIS claimed responsibility for the attack, the group’s news agency Amaq reported.
The claim could not immediately be verified. The Sunni Muslim militants are active in the area and have targeted Shiite pilgrims in the past.
ISIS has waged a campaign of kidnappings and killings since its self-proclaimed caliphate in Iraq and neighboring Syria collapsed in 2017.
