A minibus sent to collect votes from Sunni worshippers at a grand mosque in Saravan, in Iran's eastern Sistan-Baluchestan province, was set on fire, according to rights groups.

An ethnic rights advocacy group, the Baloch Campaign, reported that the bus "left the area without collecting any votes." Apparently, the blaze was put out enabling the vehicle to drive away.

This incident follows last week's violence when unidentified assailants attacked a vehicle transporting election boxes in Sistan-Baluchestan Province just minutes after voting concluded in the first round of presidential elections at midnight on June 29.

The assault reportedly resulted in the deaths of two security personnel and injuries to several others, according to Iran's state news agency IRNA. Additionally, one of the assailants was also killed.

Sistan-Baluchestan experienced significant unrest during the nationwide protests following the death of Mahsa Amini in custody, recording the highest number of casualties among Iran's 31 provinces.

The province remains a hotspot for protests fueled by unemployment, water shortages, and security policies perceived as targeting the Baluchi minority.
