Following a rare terrorist attack last week, Iran has arrested several Afghan nationals in Zahedan who have a history in acts of sabotage, Press TV reported.
"The saboteurs, who have destroyed public buildings and cars, will be handed over to Afghan guards after the completion of an investigation into their cases," said the deputy commander of the Iranian police, Brigadier-General Ahmad Reza Radan.
The arrests come after the Pakistan-based Jundullah terror group claimed responsibility for a mosque blast in Zahedan near Iran's southeastern border with Afghanistan and Pakistan. 25 people were killed and 125 others wounded in the attack.
The anti-Iran group said that the attack was part of its efforts to destabilize the country and warned of a new campaign of violence ahead of the June 12 presidential elections.
In his remarks, Radan emphasized that the Iranian police force would adopt severe measures in arresting and extraditing foreign nationals who live illegally in the country.
He explained that the culprits of such attacks have every intention to damage all unity between Shia and Sunni Muslims in Iran but will be unable to carry out their plans.
"Those individuals who intend to cause disunion in the region are neither Shia nor Sunnis. Rather they are at the service of US goals intentionally or unintentionally," Radan added.
Jundullah's ring leader, Abdolmalek Rigi, has called on Sunni clerics to dishearten people from voting, threatening to assassinate those who choose to do otherwise.
Rigi has recently admitted receiving assistance from another anti-Iran terrorist group, Mujahedin Khalq Organization (MKO), saying, "MKO has had good intelligence collaborations with us and has provided us with much information about the activities of the Iranian regime."
He has however denied any links to Washington, describing the group as a 'national movement' rather than a terrorist cell.
The MKO is listed as a terrorist organization by Iran, Iraq, Canada, and the US, but was recently removed from the European Union blacklist.
