article: Three men accused of being agents of the Syrian government have been executed in a shocking new video, Islamic State has claimed. The barbaric footage, released earlier today, shows the men kneeling in the middle of a dusty road in Deir ez-Zor, Syria, as a militant brandishing a sharpened sword stands behind them. It comes just one day after the extremist group claim to have shot and beheaded more than 30 Ethiopian Christians in Libya. Each of the men are forced on to their hands and knees in the war-torn street before they are beheaded . The harrowing video shows the sword used to kill the men being forged and sharpened for the executions . The three men were accused of being Assad agents, working for the Syrian governmment, say ISIS . The new eight-minute video shows the men - wearing orange Guantanamo-style jumpsuits with their hands and feet in chains - sitting in a dirty, underground room. After giving information about each of the prisoners in Arabic, the men are blindfolded and filmed in the back of a moving van while an ISIS militant decked in black guards over them. When the van stops, the barefoot captives are escorted out and begin to march slowly down an abandoned street, surrounded by fighters holding guns. The professionally-shot film pans the scene - showing buildings irreparably damaged by bombing - before phasing into a picture of the executioner's sword being sharpened before the brutal executions. One by one the prisoners are beheaded by a fighter, who is dressed completely in black and unidentifiable. Their bodies are left on the road. Initial reports suggested the extremist group targeted the men because they worked for the Syrian regime. But they did not confirm who the men - thought to be aged between 35 and 45 - were or when the execution took place. The prisoners were filmed barefoot and in shackles in an unknown prison at the start of the sick video . They were then blindfolded and transported in a van to the execution point - thought to be Deir ez-Zo in Syria . Sparks fly from the sword as it is sharpened, before being used to behead the men in a brutal execution . One by one the men are murdered. The body of one of the men can been seen after he was beheaded . It is the latest footage released by the militant group, which is increasingly using propaganda to encourage would-be jihadi fighters. Yesterday a 29-minute video, titled 'Until It Came To Them - Clear Evidence', showed dozens of militants holding two separate groups captive in Libya. It showed at least 16 men, described by Islamic State as the 'followers of the cross from the enemy Ethiopian Church', being shot in a desert area while 12 others were beheaded on a beach. In February a similar video was released showing the beheading of a group of 21 Coptic Christians on a beach in Libya. The helpless men were kept under a close watch by their ISIS captives. Videos of this nature - often professionally shot - are used by the militant group as propaganda to attract other would-be jihadi fighters . The bodies of each of the helpless men, thought to be aged between 35 and 45, were then left on the road . One of the victims, flanked by two fighters in black, can be seen being led down the abandoned Syrian road . ISIS has taken over large sections of iraq and ISIS and carried out multiple public executions similar to this . The battle against Islamic State amid a protracted civil war in Syria is thought to have already claimed the lives of more than 200,000 people. ISIS has destroyed churches and Christian shrines in the country. They also demanded that Christians living under its rule pay a 'special tax' known as jizya. Fighters from the Kurdish People's Protection Units (YPG) have been on the offensive and a large area is now divided between Kurdish and IS control. The extremist group has been able to gain a foothold amid chaos in Libya and is also advancing in Iraq.
