The Islamic State claimed responsibility for the bombings in a message posted on social media on Thursday.
The ministry said that the process of arresting people linked to the bombing “will certainly continue until the last person involved in supporting criminals in any way and to any extent is arrested.”
The two explosions in Kerman killed at least 89 people and injured more than 200 others, the Islamic Republic News Agency reported, citing Iranian officials. They struck as thousands of mourners gathered in the city's streets to mark the fourth anniversary of the death of Maj. Gen. Qasem Soleimani, a senior commander in Iran's Islamic Revolutionary Guard Corps who was killed in a 2020 U.S. drone strike.
Iranian authorities said that one of the suicide bombers was a Tajik national, while the nationality of the other had not been determined “finally yet.” Officials said they found two suicide vests, two remote controls and detonators, several thousand bullets and vest cords, among other items in the suicide bombers' home.
The Washington Post could not immediately verify the Intelligence Ministry's account.
