According to Fox News:
The Islamic State has released a series of horrifying photos showing blindfolded men tossed head-first off a building because, ISIS claimed, they were gay.
In photos obtained by the Middle East Media Research Institute (MEMRI), ISIS militants are shown publicly executing the unidentified men for violating Sharia law.
A crowd of spectators, including children, was gathered below the 100-foot building in Mosul as the men were held by their ankles and then sent plunging to their deaths. The photos were believed to be recent.
