One person was reported killed and eight wounded in a “terrorist” attack at a shrine in the Iranian city of Shiraz, state media reported on Sunday.
The official IRNA news agency said a gunman attempted to enter the Shah Cheragh shrine and opened fire on visitors before he could be subdued.
Shah Cheragh was the scene of another attack in October, claimed by Islamic State (IS), when 13 people died.
No group has immediately claimed the latest attack.
State media originally stated two attackers were involved and four people had been killed, but revised the figures to a lone attacker, one dead and eight injured.
