The funeral in Tarut today was for Mansour Fateel, who mourners said died from his wounds the previous day after being seriously injured in a suicide bombing attack at a Shiite mosque in the village of al-Qudeeh on May 22.
His death brings to 22 the number of people killed in that attack.
The Islamic State group claimed responsibility for that blast and another yesterday outside a Shiite mosque in nearby Dammam that authorities say killed four.
