The self-proclaimed group that called itself the Patriotic Arab Democratic movement in Ahwaz, accepted the responsibility for the attaack in a message sent on the social media on Saturday.
'The group has carried out a few sabotage operations in Khuzestan Province during the past years,' said a senior provincial police officer.
'A conscripted soldier was shot in the terror attack and later died,' Colonel Naqib Fatemi said on Saturday.
The group is supported by the foreign antagonists, including Saudi Arabia. They made several terror attacks about 13 years ago in a number of places in Ahvaz and killed a number of people.
A number of the terrorist group’s members opened fire to the people and officials attending the parade of Armed Forces on Saturday morning in Ahvaz.
The shooting claimed 10 lives and injured more than 20 others.
The number of the victims is likely to increase.
Disguised as the Islamic Revolution Guards Corps (IRGC) and Basiji (volunteer) forces, the terrorists opened fire to the authorities and people from behind the stand during the parade.
“None of the authorities were injured in the incident due to the fast reaction of the security forces”, Governor of Khuzestan Gholam-Reza Shariati told the Islamic Republic News Agency (IRNA) after the attack.
He added, “The terrorist team was annihilated, two of them were killed and other two were arrested. One of the detained terrorists is injured”.
