Iran’s security officials continue to report arrests of ISIS suspects in the wake of the twin June 7 attacks on the Iranian parliament and a mausoleum that left 17 people dead.

The national police commander, Hossein Ashtari announced on Saturday that a “terrorist team” has been arrested around Tehran, the capital city. He has not provided any further details.

According to the official government news agency IRNA, Ashtari said, “The good cooperation of citizens” has been effective in identifying the suspects. The night before, the police had announced the arrest of one more suspect in Karaj, near Tehran.

Islamic State claimed responsibility for the suicide bombings and gun attacks on parliament and the mausoleum of the Islamic Republic's founder, Ayatollah Khomeini.

On June 9, security officials announced that a total of 41 people had been arrested in connection with terror networks.

Various Iranian officials continue to announce arrests and it is not always clear whether they are talking about the same cases or each time different suspects are involved. So far, no video footage or other material evidence has been published about the arrests.

Iranian officials, including the Supreme Leader, Ayatollah Ali Khamenei have accused the U.S. and Saudi Arabia in having a hand in the Tehran attacks.
