Shooting at Iranian parliament reported from Tehran

Two semi-official Iranian news agencies, Fars and Mehr, reported on Wednesday a shooting at the Iranian parliament. "A person entered Iranian parliament today and started shooting at the guards. He shot one of the guards in the leg and ran away," the agencies reported on their telegram feeds. There is no independent verification of this or any other reports on the incident.
The Tasnim news agency, run by Iran's Revolutionary Guard Corps, reported shortly afterwards that there were three gunmen, and that the shooting was still underway.
