The Watermark of 1000 Rials Note - Shahid (Martyr) Mohammed Hossein Fahmideh

Iranian children participate in a city race on the 13th of Aban (November 3).
The race is held on this day to honor the memory of Hossain Fahmideh who strapped a grenade pack on his back and blew himself up under a tank. Hossain was a 13 year-old boy when he blew himself up.
The brainwashed kids seem to know the story well
