"One of the biggest takfiri terrorist plots was discovered and foiled," the official IRNA news agency quoted the ministry as saying, using terms applied by Iran to extremist groups.
"A series of bomb attacks prepared in various areas deep inside the country and especially in Tehran and some other provinces... were foiled, the terrorists were arrested and a number of ready-made bombs were recovered," it said.
No more details were provided. The ministry said more information would come following investigations "both inside and outside the country."
