Several casualties in terror attack on military parade in Ahvaz

Islamic State carried out a deadly assault on parliament and the shrine of Ayatollah Ruhollah Khomeini in Tehran in June last year. At that point, that had been the only attack by the Sunni extremists inside Shia Iran, which has been deeply involved in the wars in Iraq and Syria where Isis once held vast territory. Ahvaz is the capital of Iran’s oil-rich Khuzestan province, where Arab separatists have attacked oil pipelines in the past.​​​​​​​
