UPDATE: ISIS claimed responsibility for the attack via its news agency Amaq.
Up to 24 people were killed and over 50 others were injured in a terrorist attack on a military parade in the Iranian city of Ahvaz on September 22, according to the Iranian media.
According to reports, gunmen opened fire from behind the stands during the military parade. The attack was ongoing several minutes during the event, which featured troops from the Iranian Army’s 92nd armored division.
The terrorists were apparently wearing military uniforms. Two of the four attackers were killed during clashes with Iranian troops. Two others were detained.
Following the incident, Foreign Minister Mohammad Javad Zarif stated that Iran will respond “swiftly and decisively” in defense of its people.
“Terrorists recruited, trained, armed, and paid by a foreign regime have attacked Ahvaz. Children and journos [are] among casualties,” Zarif tweeted.
He added that Iran holds “regional terror sponsors” and their “US masters” responsible for the attack.
