Gunmen killed three members of Iran's Revolutionary Guard on the event date of December 10, 2025, in Sistan and Baluchistan province near the Pakistan border, according to state media. The attack took place in a mountainous area near the city of Lar, about 1,125 kilometers southeast of Tehran, making it another reminder of how volatile Iran's far southeast remains even when the country is focused on other national pressures.
The official IRNA news agency said the Guard members were ambushed while patrolling. It did not report whether any other Guard members were injured, and it said the attackers remained at large as the Guard pursued them and called them terrorists. No group claimed responsibility, which leaves the incident in the familiar gray zone of borderland violence where official blame arrives before clear attribution does.
The province bordering Afghanistan and Pakistan is one of the least developed in Iran and has long been the site of clashes involving militant groups, armed drug smugglers and security forces. The source points to a recurring pattern rather than a one-off attack: in August, security forces killed 13 militants in three separate operations there, a week after the same area saw militants kill five policemen on patrol. That history helps explain why the Guard response is likely to be both immediate and forceful.
For the Revolutionary Guard, the ambush is significant not simply because of the fatalities, but because it happened in a region where the state has repeatedly tried to suppress armed threats without ending them. The terrain, the border location and the mix of insurgency and smuggling all make these incidents difficult to contain, and the source does not suggest the latest attackers have been identified.
The report therefore stays with what is verified: three Guard members were killed, the attackers are still being hunted, and Sistan and Baluchistan remains one of the most dangerous edges of Iran's security map.
The attack fits a long pattern in Sistan and Baluchistan, where the state faces not just one adversary but overlapping threats from insurgents, smugglers and armed groups that can exploit terrain and border proximity. The source's reference to previous operations in August suggests that the area can swing quickly from militant action to security sweeps and back again. That makes the province strategically important and politically sensitive for Tehran, which cannot afford repeated losses among its elite forces without responding. Because no group claimed responsibility, the attack remains unresolved, but the broader significance is visible already: in one of Iran's most neglected border provinces, even a routine patrol can end in an ambush that reverberates far beyond the mountains where it happened.
That pattern matters because Sistan and Baluchistan is not just a distant border province; it is a security pressure point for Tehran. The Guard's pursuit of the attackers suggests the state expects a fast response, but the source does not say the ambush has been resolved. For now, the only confirmed outcome is that three members of the Revolutionary Guard were killed on patrol in a part of Iran where deadly clashes remain stubbornly common.
