Iran: Islamic State (ISIS) claims responsibility for deadly Iran bombing
ISIS has claimed responsibility for a deadly Iran bombing that killed more than 80 people and wounded scores more.
ISIS, seen as a terrorist group by most of the world, said in a widely circulated statement that suicide bombers detonated explosive belts in the middle of the crowd that had gathered in the southeastern Iranian city of Kerman.
ISIS, an anti-Shia and anti-Iranian faction, has fought against Iran for years across the Middle East, and though largely defeated, it maintains a presence in the region.
A U.S. official on Wednesday said the working theory is that ISIS carried out the bombing, saying it was consistent with previous attacks.
