A truck bomb has ripped through parked buses in a petrol station loaded with Shia pilgrims, killing at least 100 people, mainly Iranians, returning from the Arbaeen commemoration.
ISIS has claimed responsibility for the attack, which also wounded 45 people.
Officials said the target of the attack appears to have been buses carrying Iranian pilgrims heading home after taking part in Arbaeen major Shia holiday in the holy city of Karbala.
