US is currently training Iraqi soldiers to retake Iraq's second largest city

ISIS are preparing to move headquarters there from stronghold in Mosul

through that same city

Eight dead bodies hang from a metal frame in the Iraq's Kirkuk province in Islamic State's latest public display of barbarity.

The gruesome images which emerged on social media show the men's limp bodies suspended from their feet off a tall structure in the town of Hawija.

The notorious black flag used by Islamist groups like ISIS is displayed above them as horrified onlookers inspect the scene.

Some of the deceased men appear to be wearing military fatigues but it is not known if they were Iraqi soldiers.

An ISIS fighter believed to be Abu Al-Rahman poses triumphantly in one of the pictures - giving the one-fingered salute in front of a bloodied victim's corpse.

Barbarity: Eight men were found hanging from their feet in the Iraqi city of Hawija in the militants' latest public display of death

Gruesome: The dead men were suspended from a tall structure in the same city that Syrian soldiers were paraded through the streets in cages

Hallmark of terror: The notorious black flag used by extremist Jihadi groups like ISIS hung above the deceased men

Death: It is unknown whether the men were Iraqi soldiers, as ISIS' presence in the northern-Iraqi city grows

The same tyrant has been been pictured before alongside severed heads and masked ISIS fighters.

A shocking video released in February showed orange-clad captives being paraded in cages in the same city of Hawija.

Frenzied crowds taunted the kidnapped men during the merciless procession which echoed the terrible death suffered by captured Jordanian pilot Moaz al-Kasasbeh.

He was also caged before a film of him being burned alive, implying the same fate would befall the trapped captives in Hawija.

It was seen as revenge against the Kurdish forces who dragged the bodies of ISIS fighters through the streets of northern-Iraq earlier that month.

Previous reports suggest he is an Iraqi national from the town of Almere and the heads once belonged to members of the Syrian army whom the militants captured and beheaded.

The extremist group has established a firm foothold in what was once an oil-rich Kurdish stronghold of Kirkuk.

ISIS has been preparing a new base for its deadly operations in Hawija as the United States train Iraqi troops for an invasion to retake Mosul, the International Business Times reports.

Terrorist: The man pictured posing alongside the suspended men is believed to be Abu Al-Rahman

Islamic State: The same man has been previously been pictured alongside armed, masked fighters believed to belong to ISIS

History of terror: Al-Rahman has also been photographed giving the one-fingered ISIS salute in front of several decapitated heads

Hawija is a predominantly Sunni Muslim town which lies off a major highway leading to Mosul and the capital Baghdad.

Since ISIS first invaded the city in June 2014, it progressively conquered neighbouring villages until it gained enough support from locals to establish its new headquarters there.

Over the last nine months, its main base in Iraq has been in Iraq's second-largest city Mosul which it took over last year.

It has offered Islamic State a military advantage due to its proximity to the Syrian border, which allows them to smuggle both weapons and soldiers.

But a US-led coalition has attacked the city with airstrikes for many months - targeting ISIS convoys and weapons stores.

The Americans are now training over 20,000 Iraqi soldiers to retake the city from Islamic State's deadly grip, US Cnetral Command has revealed.

Their presence in Hawija gives the militants access to Anbar province and another road leading to the Baiji oil refinery they lost to the Iraqi military in November 2014.

Hawija has been a hotbed of violence April 2013 - two years after the US withdrew its troops from the country.

It began when the government's forces raided a camp of rebels in the city on April 24 and killed dozens of civilians in the process.
