Thirty-five people were arrested in relation to the Jan. 3 attacks in the southeastern city of Kerman which killed 94 people, the Iranian Intelligence Ministry said on Thursday according to semi-official Tasnim news agency.
The ministry said it has so far identified one of the two suicide bombers as a national of Tajikistan who entered Iran illegally on December 19.
Iranian President Ebrahim Raisi and Revolutionary Guard Corps (IRGC) Commander Hossein Salami have vowed revenge during the funeral of the victims of the Kerman attack.
Last Thursday, ISIS claimed responsibility for the two explosions, saying two militants detonated explosive belts in the crowd that gathered at a memorial for al-Quds Force Commander Qassem Soleimani, who was killed in a US airstrike in Baghdad in early 2020.
