Twisted ISIS executioner dangles gay men by ankles before dropping them 100ft below

Warped Islamic State militants brutally executed three gay men by throwing them from the top of a high rise building.

A bloodthirsty mob of hundreds - including children - stopped cars in the middle of the road to watch the horrific atrocity unfold.

Many were armed with stones and rocks to finish off the victims, if any of them survived.

The men appeared to have both their hands tied waiting in line as they watched the first victim being dropped.  

Crowds stood and watched the men being executed in front of armed and masked ISIS fighters and religious officials.

The pictures were posted online with the caption 'In the name of God the Merciful', claiming to be from the Islamic State's 'Information Office'.

They were believed to be taken in ISIS stronghold Mosul, Iraq.Last month, ISIS released horrific images showing a man stoned to death for being gay.

A senior U.S. envoy said on Wednesday the growth of ISIS could "wreak havoc on the progress of humanity." Meanwhile, retired Gen. John Allen was appointed by U.S. President Barack Obama to build a coalition against the religious extremists.

Last month, the Iraqi government had its worst military setback in nearly a year when ISIS seized Ramadi from a weakened Iraqi army.

In May, Gen. John Allen told a conference ISIS was "a regional problem trending towards global implications".
