The country’s state news agency IRNA reported that several people had been arrested and are being interrogated.
Ammunition and bombs have also been seized, IRNA said.
The ministry said in a statement on state TV, “In a criminal plot of the anti-Islamic terrorist takfiri groups, a series of bombings had been planned in several places of the country for the coming days … the terrorists were arrested and some bombs and a huge amount of explosives were seized.”
Semi-official Fars news agency is said to have reported that Ali Shamkhani, the secretary of Iran’s Supreme National Security Council has said that the attack was planned for the Muslim holy month of Ramadan.
The arrested have reportedly not been identified but have been called ‘takfiris’.
‘Takfiris’ is a derogatory term which refers to Muslims who accuse others of being non-believers. Sunni militants Islamic State (ISIS) group is often referred to as ‘takfiris’ by Iranian authorities.
Mehr news agency meanwhile reported that the attacks had been planned by Wahhabi Takfiri groups. Wahabism is a school of Islam which is practiced in Saudi Arabia.
According to reports, relations between Iran and Saudi Arabia had been troubled since the execution of a prominent Shiite cleric in January this year.
Public relations office of the Intelligence Ministry said, “Given that field investigations are still being undertaken inside and outside the country as well as that terrorists are being interrogated, supplementary information will be delivered to the honourable Iranian nation as soon as security conditions will allow.”
