The claim for Friday's bombing, which was posted on a Facebook page used by the extremist group, said a "soldier of the caliphate" identified as Abu Jandal al-Jazrawi, blew himself up among "an evil gathering of those filth in front of one of their shrines in Dammam."
It called on Sunnis to "purify the land of the two shrines from the atheist rafida," a derogatory term for Shiites.
The extremist group has repeatedly called for attacks on the kingdom and carried out a bombing at a Shiite mosque earlier this month that killed 21 people.
