Iran has thwarted one of the biggest terrorist plots in Tehran recently, the intelligence ministry said on Monday.
"The anti-Islamist Takfiri group had schemed to carry out a series of bombings in different parts of the country (including in Tehran) on the occasions to come," Xinhua news agency cited a statement as saying.
"In the operations, the terrorists were detained and a number of bombs, ready to explode, and a sizeable amount of materials for making bombs were seized," the statement said.
Further disclosures will be made as the investigation process advances, it added.
