Iranian intelligence forces have detained 27 terrorists linked to ISIS who planned to carry out terrorist operations in religious cities inside the country, ABC cited Iran's intelligence ministry on Tuesday.
In a statement, the ministry said that they were identified during an exchange of intelligence with one of the regional services, ahead of President Hassan Rouhani's inauguration.
The report did not say which country Iran exchanged the intelligence with, or mention where they were arrested.
It said 10 of them were detained at a "control center" abroad, and sent to Iran, while 17 others were arrested in Iran.
The ministry added five of them had planned to carry out terror attacks inside Iran and the others were their supporters.
