A 17-year-old schoolboy has died in Iran’s second largest city, Mashhad, after reportedly being shot at close range by state forces during anti-government protests.

Abolfazl Adinezadeh’s death certificate showed that he died of liver and kidney damage caused by birdshot, according to a BBC Persian report. A doctor was cited as estimating the distance from which the teenager was shot on 8 October as less than 1 metre.
