Ten Iranian border guards were killed in an attack in the restive Sistan-Baluchestan province on Saturday, according to an Interior Ministry statement on X.

"Following the martyrdom of 10 border guards on the Goharkouh road in Taftan County, the Minister of Interior promptly assigned a team of police commanders and Ministry of Interior officials to investigate the details of this incident," the statement added.

The insurgent Sunni Baloch group Jaish al-Adl claimed responsibility for the attack.

Iran's Sistan-Baluchestan province has been the site of numerous attacks attributed to Jaish al-Adl, a group known for its history of ambushes, bombings, and other violent operations, resulting in the deaths of both civilians and security personnel.

Jaish al-Adl advocates for an independent Balochistan that encompasses Baloch populations on both sides of the Iran-Pakistan border. The group has conducted numerous significant operations in Iran's southeastern region.

In June, Jaish al-Adl announced the identification and apprehension of nine key members of a "terrorist and espionage" network associated with the Revolutionary Guards, comprising Iranian and Pakistani nationals as well as former members of the Afghan government's armed forces.

One of the most intense confrontations between the group and Iranian border forces occurred in April when Jaish al-Adl launched simultaneous attacks on five public locations, as well as military and law enforcement bases in Chabahar and Rask.

The Baloch community, alongside the Kurds, has long been one of the most persecuted minorities in Iran. The region is among the country’s most impoverished, characterized by high unemployment rates and inadequate infrastructure. As a result, many residents have turned to smuggling fuel, goods, and, in some cases, drugs as a vital means of survival.
