One person was killed, and three others were injured during an armed conflict on Saturday evening in Zahedan with Basij militia forces deployed to the scene.

The conservative website Tabnak wrote initial reports indicating that a "terrorist team" was identified and encircled by security forces on Kowsar Street in Zahedan.

However, the Fars News Agency, which is associated with the Revolutionary Guards, attributed the incident to personal disputes, though it did not provide additional details.

Halvash news which covers the province, said a more extensive security presence, including plainclothes agents, had been deployed to the scene as fighting lasted for around two hours, with a reconnaissance drone spotted monitoring the situation.

This latest incident in Zahedan occurs against the backdrop of heightened regional instability. On April 4, clashes in two southern cities of the Sistan-Baluchestan province resulted in over 20 deaths involving security forces and members of the Jaish al-Adl militant group.

In related developments, the Southeast Headquarters of the Ground Forces of the Revolutionary Guards announced the recent arrest of several individuals at a religious school in Rask. The suspects were accused of supporting the insurgent Sunni Baluch group Jaish al-Adl. The Revolutionary Guards claim the cooperation of local residents facilitated the arrests.

Jaish al-Adl, however, has denied any affiliation with those detained, condemning the arrests as "a clear lie and conspiracy." The group, which is designated as a terrorist organization by Iran and several Western governments, warned of potential repercussions and advised against further provocations.

“The security apparatus of the regime must be aware that such actions are a clear provocation of the Jaish al-Adl organization…, and as such, these acts could have unpredictable consequences for our land,” read the group’s statement.
