Several suspects have been arrested and are under interrogation over the plot after agents seized ammunition and bombs, the state TV said on Monday.
The semi-official Fars news agency quoted Ali Shamkhani, the secretary of Iran’s Supreme National Security Council, as saying the attack was timed to hit during the Muslim holy month of Ramadan.
Iran thwarts major ‘terrorist plot’
“One of the biggest takfiri-Wahhabi terrorist plots was discovered and foiled,” the official IRNA news agency quoted the ministry as saying, using terms applied by Iran to Sunni 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.”
