The suspected mastermind behind the deadly attack on a military parade in Iran in September has been killed in Iraq, according to reports from the Iranian Revolutionary Guard Corps.
Abu Sahi, one of the leaders of the extremist militia group Islamic State, was killed by "resistance units" along with four other suspected terrorists in Iraq's eastern province Diyala, the IRGC told the Iranian news agency ISNA on Wednesday.
Who the "resistance units" were was not clarified in the report.
The attack took place on September 22 in the southwestern city of Ahvaz, where a military parade was being held to commemorate the start of the Iran-Iraq war in 1980.
Militants opened fire on the parade marchers, killing 25 people, including soldiers from Iran's Revolutionary Guard as well as civilians. More than 60 people were injured in the attack.
Iranian intelligence authorities later detained 22 individuals with links to the separatist Al Ahvazieh militant group.
Tehran says Al Ahvazieh, which claimed responsibility, is supported by its rivals Saudi Arabia and the United Arab Emirates (UAE), who are allies of the U.S., and that the group has close ties to the Islamic State militia.
Iran has yet to offer proof of its claims that any foreign powers were behind the attack.
