The agency quoted Fadahossein Maleki, a lawmaker from the Sistan-Baluchistan province near the Pakistani border where the attack took place, as blaming a Sunni separatist group affiliated with al-Qaida, known as Jeish al-Adl, for allegedly being behind the attack.
There was no claim of responsibility for the bombing and ISNA did not identify the wounded Revolutionary Guard commander.
Jeish al-Adl — meaning Army of Justice in English — has been behind several attacks in Iran in recent years. Iran says it operates from across the border in Pakistan.
The southeastern Sistan-Baluchistan province has been scene of occasional clashes between government forces and militants, as well as armed drug smugglers.
In 2019, a suicide car bomber claimed by Jeish al-Adl attacked a bus carrying members of the Revolutionary Guard force, killing 27 troops.
