Members of Iran’s security forces killed in a firefight with an unnamed ‘terrorist group’, state media reports.

The Islamic Revolutionary Guard Corps (IRGC) says four members of Iran’s security forces were killed in a firefight near the Pakistan border.

One member of the elite force, named Mohammad Goudarzi, and three members of the Basij forces – operating under the IRGC – were killed after a fight with an unnamed “terrorist group”

The incident reportedly took place in Saravan, in the southeastern province of Sistan and Balochistan, near the Pakistani border.

The IRGC did not say the fighting was linked to the country’s ongoing unrest amid protests that erupted in mid-September after the death in custody of Mahsa Amini

But it has previously accused “separatist” and “terrorist” groups in the border areas of both Sistan and Balochistan – where a majority of Iran’s ethnic Balochis live

Sistan and Balochistan has seen some of the deadliest events since the beginning of the protests.

That includes an incident on September 30, when Amnesty International said dozens were killed by security forces.
