ISIS militants were thrown off a cliff before shooting them by Iraqi troops, however, the Iraqi government is investigating it.
In the video, the terrified man is ridiculed and beaten by several rifle-wielding troops before being slowly forced up to a cliff and thrown onto the still body of another man below.
The execution method is suggestive of one employed by ISIS, which is notorious for killing people it decides are guilty of homosexuality by throwing them from high buildings.
According to the BBC, an interior ministry spokesman said that if the video, supposedly filmed in recently-liberated Mosul – was genuine then the soldiers involved will be brought to justice.
There have been reports by human rights groups that some Iraqi government troops are guilty of torture and execution in the war against ISIS.
One man, Falah Aziz, claimed to have beheaded 50 ISIS fighters and stressed he was completely ‘at ease’ doing so.
The video of the man being thrown from the cliff, which was posted to the Mosul Eye blog yesterday, comes just days after a US-backed coalition of Iraqi forces announced it had freed Mosul, the city in which ISIS proclaimed its caliphate in 2014.
However, small-scale fights are still going on inside the Old City, with an unknown number of ISIS troops – perhaps as many as hundreds – hiding out.
Speaking to the BBC, Belkis Wille, senior researcher at Human Rights Watch, said: ‘In the final weeks of the battle for west Mosul, the pervasive attitude that I have observed among armed forces has been of momentum, the desire to get the battle wrapped up as quickly as possible, and a collapse of adherences to the laws of war.’
She added: ‘These reports have been met with congratulations from Baghdad on the victory, only further fostering the feeling of impunity among armed forces in Mosul.’
