The official Iranian news agency Tasnim says two members of the Islamic Revolutionary Guard Corps (IRGC) were killed by unidentified gunmen in the southeastern city of Zahedan.
"Guards Colonel "Mehdi Molashahi" and Basij brother "Javad Kikha" from the personnel of the Salman Corps of Sistan and Baluchistan were shot by unknown people in...Zahedan and were martyred," the agency said in a tweet on October 25.
The agency said an investigation into the shooting had started.
It gave no further details of the incident, which comes amid weeks of unrest over the death of a young woman while in police custody for wearing a head scarf, or hijab, improperly.
Authorities have responded with a brutal crackdown that has left dozens dead in Zahedan, the capital of Sistan-Baluchistan province, which borders Pakistan.
