Iran’s judiciary announced that two men were hanged on Sunday over charges relating to anti-government protests that peaked in January, having begun a month earlier over economic grievances.

The two men, Erfan Esfandiari and Gol-Mohammad Mohammadi, were found guilty of “tying police officers to a road sign with ropes, injuring them with stones, dousing them with gasoline, and setting them on fire” in the central city of Isfahan, said the judiciary.

The indictment stated that the two individuals had “filmed the scene of the killing and transmitted the footage to television channels” abroad.

The statement did not specify the dates of their arrest or trial, and did not give the men’s ages.

In late December, a protest movement initially sparked by the high cost of living rapidly evolved into widespread anti-government demonstrations that peaked on January 8 and 9.
