TEHRAN: Dozens of suspected "agents" of the Islamic State group have been arrested following the deadly attacks in Tehran, Iran's intelligence ministry and a website close to the judiciary said Friday.
The militant group claimed responsibility for Wednesday's attacks that killed 17 people.
The intelligence ministry said 41 suspects were arrested in Tehran, in the northwestern provinces of Kermanshah and Kurdistan, and in West Azerbaijan, near the borders with Iraq and Turkey.
It described the suspects as "agents of Daesh", an Arabic acronym for the Islamic State group, and said they included "operational teams".
Documents and equipment "for carrying out terrorist operations" were also seized, the ministry said in a statement.
Earlier, the Mizanonline website close to the judiciary said nine people suspected of links to IS were arrested on Thursday and Friday in the southern province of Fars and in Kermanshah.
The attacks on Tehran's parliament complex and the shrine of revolutionary leader Ayatollah Ruhollah Khomeini also wounded more than 50 people and were the first claimed by IS in Iran.
