Jihadis fighting for the Islamic State in Libya have filmed themselves brutally murdering a Tunisian baker after accusing him of spying on behalf of the terror group's enemies.

Sickening video footage shared on social media showed masked militants interviewing the 39-year-old man before dragging him out into the street and shooting him in the back of the head.

The man is understood to have owned a bakery in the city of Benghazi, which is on the front line in fierce fighting between the Libyan and ISIS-affiliated terrorists, as well as militants loyal to other Islamist groups in the war-torn country.

Prisoner: The horrific video of the man's so-called execution begins with him being interviewed in a dark room while wearing an orange jumpsuit - the now notorious hallmark of ISIS' gruesome executions videos

Dead on the floor: Another masked militant then steps forward and shoots the victim several times in the back of the head as the group should 'Allahu Akbar' - an Islamic phrase meaning God is the greatest

The identity of the victim has to be revealed but ISIS themselves claimed he was a 39-year-old man on Tunisian origin who owned a small bakers in the city of Benghazi.

The jihadis accused him of spying on the terror group's activities in the city and secretly reporting back to soldiers loyal to the Libyan regime who used that information to stage targeted attacks.

The horrific video of the man's so-called execution begins with him being interviewed in a dark room while wearing an orange jumpsuit - the now notorious hallmark of ISIS' gruesome executions videos.

The next sequence shows him being led out into a public square by a group of armed men who force him down on his knees.

One of the jihadis reads the charges against him, ending his rant with a cry of 'death to espionage'.

'I WILL NEVER EVER LOVE ANYONE BUT HIM': BRITISH PUNK JIHADI 'MRS TERROR' TWEETS HER PRIDE AFTER ISIS FANATIC HUSBAND IS WIPED OUT IN SYRIA DRONE STRIKE A middle-aged punk rocker dubbed 'Mrs Terror' when she fled the UK to join ISIS has tweeted chilling messages of pride after her British ISIS fanatic was killed in an American drone strike. Mother-of-two Sally Jones, 45, took to Twitter overnight to say she 'will never love anyone' other than computer hacker and foreign jihadi recruiter Junaid Hussain, 21. She added that she was 'proud' that her husband was killed by 'the biggest enemy of Allah' and dubbed the anti-ISIS coalition as 'Crusaders' for carrying out airstrikes on the terror group. Hussain, who was originally from Birmingham, died last month after a U.S. drone struck the car he was travelling in through ISIS' de facto capital city Raqqa. He was widely reported as number three on America's ISIS target list due to his hacking credentials and key role in recruiting foreign fighters. Advertisement

The man was said to be a 39-year-old baker living in Benghazi, cradle of the 2011 revolution that ousted dictator Moamer Kadhafi and plunged the country into chaos that continues to the present.

Libya currently has two rival governments and several armed groups vying for control of the country and its oil wealth, and Islamist extremists have exploited the turmoil to establish a foothold.

Two Tunisian journalists, Sofiene Churab and Nadhir Ktari, disappeared in Libya a year ago.

ISIS announced in January that it had executed them, but the foreign ministry in Tunis recently said it had 'irrefutable proof' they are still alive.

Today's sickening video comes just days after the Libyan branch of ISIS appeared to announce the election of a mysterious new leader, Abul-Mughirah al-Qahtani.

In the latest issue of the terror group's propaganda magazine Dabiq, Qahtani is referred to as ISIS' 'delegated leader for the Libyan State'.

The statement effectively suggests that Qahtani has replaced either one of both of the two men previously identified as the de facto head of the organisation in the North Africa: Libyan national Hassan al-Karami and Bahraini cleric Turki bin Mubarak al-Ben Ali.

However there is significant confusion over the issue, with Business Insider quoting one expert as saying that Qahtani, should he actually exist, is a completely new name to jihadi watchers in the country, adding that it raises the question of whether the militant runs ISIS' Libyan branch remotely.

While ISIS militants are carrying out savage murders in Libya, their cohorts in war torn Syria are taking part in equally brutal murders.

Gruesome new images released today show the terror group executing two blindfolded men in front of a baying group of supporters in the Damascus suburb of Al-Hajar al-Aswad.

There was little evidence of why the men were killed, but ISIS has been pushing deeper and deeper into the Syrian capital in recent weeks,

But while the militants are wreaking havoc in the vast swathes of territory under their control in North Africa and the Middle East, Iraqi security services managed to capture at least 12 men suspected of being members of the terror group.

The detained men were seen being lined up against a wall amid the rubble of a partially destroyed building in the frontline city of Kirkuk.

With plastic bags over their heads and their arms bound behind their backs, the accused men appeared exhausted after being captured during running battles for control of the city.
