According to Iran’s Interior Minister Abdolreza Rahmani Fazli, 25 terrorist groups were busted during last month’s religious commemorations of Arbaeen.

Rahmani Fazli announced on Tuesday that the terrorist groups were disbanded following an extensive intelligence and security operation.

Twenty terrorist groups which aimed at conducting terrorist attacks were identified and broken up, the Iranian minister said.

“[Members of] five other terrorist groups were also arrested,” he maintained.

Rahmani Fazli further said that great effort was made to guarantee the security of the Arbaeen rituals.

“Despite all the security measures, two terrorist attacks were carried out,” he said, expressing hope that such events would not happen again.

Nearly 100 people were killed after a bomb placed inside a truck went off at a gas station in the Shomali village in the suburbs of al-Hilla,100 km south of Baghdad, on November 24.

Most of the victims were Shia Iranian pilgrims who were en route back to Iran from the Iraqi holy city of Karbala, where they had attended the greatest gathering throughout the world dubbed Arbaeen march.

Arbaeen marks the 40th day after the martyrdom anniversary of Imam Hussein, the third Shia Imam.

ISIS claimed responsibility for the attack in an online statement.

At least eight other people were killed and six sustained injuries in another terrorist attack carried out by ISIS in the Iraqi town of Ain al-Tamer, west of Karbala on November 14.
