Eight Iranian border guards were killed in a clash with Sunni rebels who had infiltrated from neighboring Pakistan, Iran’s official IRNA news agency reported on Tuesday.
The attack occurred in a border area in the southeastern town of Negur in the Sistan-Baluchistan province.
“Armed terrorists entered Iran from Pakistan and clashed with border guards, killing eight soldiers before fleeing back to Pakistan,” Ali Asghar Mirshekari, deputy governor of Sistan-Baluchistan province, told the news agency.
Three gunmen were also killed by Iranian security forces. An official request had been made to Pakistani authorities to launch an investigation into the incident and apprehend the assailants, who had fled back into Pakistan, PressTV reported.
The restive region has known violence in the past, both from domestic Baloch separatists who seek independence from Tehran as well as Sunni militant groups operating from Pakistan.
Iran has repeatedly requested Pakistan to rein in Islamist groups based in the border zone.
