Iranian intelligence forces have arrested two members of the Daesh Khorasan terrorist group, according to reports by local news agencies.
The semi-official Mehr and ILNA news agencies said in reports on Tuesday that the two terrorists had been trying to enter the holy shrine of Hazrat Masumeh (AS) in the northern city of Qom earlier in the day when they were arrested.
The arrests were made by the intelligence unit of the local branch of the Islamic Revolution Guards Corps (IRGC), the reports said.
Images of the two terrorists were also published in the reports, showing they were seeking to enter as ordinary pilgrims into the shrine, which is the second most important pilgrimage site in Iran.
The IS-K, known in Iran and in the region as Daesh Khorasan, was responsible for twin bombings in January in the southeastern Iranian city of Kerman which killed more than 90 people.
The group also claimed a shooting attack last month on a concert hall near the Russian capital Moscow which killed at least 144 people.
A Monday report by the Reuters news agency showed that Iran had arrested dozens of Daesh Khorasan members after the terrorist attacks in Kerman.
It cited unidentified sources as saying that the Iranian authorities had obtained intelligence in interrogations of those arrested that showed the the group was planning a major attack in Russia. The report said Iran had shared the information with Russia.
Iran has suffered a couple of terrorist attacks in recent years by Daesh, which controlled large swathes of land in Iraq and Syria until it was declared territoriality defeated in 2017.
