At least 24 people were killed and another 53 were injured in a terrorist attack carried out during a military parade in southern Iran’s Ahvaz on Saturday, the IRNA news agency reported.

At least eight members of Iran's Revolutionary Guard Corps (IRGC), an elite military force, died in the attack, the Tasnim news agency reported earlier.

The Patriotic Arab Democratic Movement in Ahwaz has claimed responsibility for the attack.

Four gunmen in a military uniform opened fire at the crowd from behind the stand, the reports said. The shooting lasted for about 10 minutes. Two gunmen were killed and two others were detained.

According to a spokesman for Iran's IRGC, the terrorists targeted both the military and the civilians, who had been invited to attend the event.
