After the attack, Ahmadinejad switched vehicles and was soon standing on a platform in the town center and making a speech televised live.
Hamadan’s population is purely Iranian Shiite with none of the ethnic or religious minorities persecuted by the regime. It is located on the site of the Biblical Shushan, several hundreds kilometers west of Tehran.
