Iranian Interior Minister Mostafa Mohammad-Najjar says nine individuals have been arrested in connection with the Zahedan terrorist attack, which left 27 people dead, Press TV reported.
"Two have been indicted and seven individuals are suspected of aiding and abetting the perpetrators of the attack," said Mohammad-Najjar.
The Iranian minster went on to reveal measures taken to immobilize terrorists, saying, "We blocked the path that these individuals used in a bid to counter them. In doing so clashes occurred in which nine rebels were killed," IRNA reported on Wednesday.
Mohammad-Najjar went on to say that a string of security and intelligence measures have been taken in terms of border control and imposing restrictions on movement from neighboring countries.
On July 15, two bombs were detonated in quick succession in front of the Zahedan Grand Mosque in Sistan-Baluchestan Province.
At least 27 people lost their lives and more than 270 others were injured in the incident, which was blamed on extremist Wahhabis and Salafis trained by US intelligence in Pakistan.
