At least 24 people were killed in an attack at an Iran military parade in Ahvaz, says local state media.
Unidentified gunmen have opened fire on an Iranian military parade in the south-western city of Ahvaz, killing at least two dozens of people, including civilians, and injuring more than 50, state media say.
Meanwhile, local reports said that the attackers shot from a park near the parade and were wearing military uniforms.
An anti-government Arab group, Ahvaz National Resistance, claimed the attack.
The foreign minister has blamed “terrorists paid by a foreign regime”.
Iran is marking the anniversary of the beginning of the 1980-88 war with Iraq with several military parades across the nation.
Fars news agency said the attack started at 09:00 local time (06:30 BST), lasted about 10 minutes, and appeared to involve four gunmen.
The news outlet also said that the attackers fired at civilians and attempted to attack military officials on the podium.
Eight members of Iran’s Revolutionary Guard and a journalist are among those killed, reports say.
“There are a number of non-military victims, including women and children who had come to watch the parade,” Irna news agency said.
As of posting, there have been conflicting reports whether who are behind the attack.
A spokesman for the Ahvaz National Resistance, an umbrella group that claims to defend the rights of the Arab minority in Khuzestan, said the group was behind the attack, as reported in BBC news.
The spokesman did not say whether the group had links to other countries.
