Depraved jihadis fighting for the Islamic State in Iraq have started using chickens as mobile improvised explosive devices, it has been claimed.

Members of the terror group operating in and around the city of Fallujah are said to be strapping explosive belts to chickens, which are then encouraged to wander into enemy camps.

Once the chickens are successfully within striking distance without having aroused suspicion, the ISIS extremists apparently use remote controls to set off the devices, killing all those close by.

Suicide chickens: ISIS jihadis operating in and around the city of Fallujah are said to be strapping the explosive belts to chickens, which are then encouraged to wander into enemy camps

Images of so-called 'suicide chickens' have been widely shared online by both pro and anti ISIS users, although their authenticity could not be verified.

Details of why the terror group are apparently using exploding birds were told to the Daily Star.

The crude devices show how ISIS is running low on ammunition following several years of all out war in Syria and Iraq, the newspaper quoted unnamed experts as saying.

'ISIS will use whatever means they can to bring death and destruction. Using animals has little military value - it is just another example of how their twisted minds enjoy dreaming up bizarre ways to kill people,' a unnamed British man fighting alongside Kurdish troops in the region added.

The bizarre claims that ISIS are using suicide chickens comes just days after reports of the terror group strapping IEDS to a goat that was sent into a Kurdish base in the Syrian city of Kobane.

Terror: The crude devices show how ISIS is running low on ammunition following several years of all out war

GAZA ROCKED BY ISIS CAR BOMBS ON HAMAS AND ISLAMIC JIHAD AS EXTREMIST GROUPS CONTINUE TO STRUGGLE FOR POWER ISIS are thought to have been behind five co-ordinated car-bomb attacks in Gaza yesterday, targeting members of Hamas and Islamic Jihad. The devastating blasts rocked a quiet area in the north of Gaza city, destroying five cars thought to belong to members of the Ezzedine al-Qassam and Al-Quds brigades. The attacks come amid growing tensions between the Palestinian territory's rulers and extremist opponents. Several people reportedly suffered minor injuries in the attacks. Yesterday's attacks are believed to be the work of hardline ISIS supporters, looking to destabilise Hamas' control of the strip. Some accounts claim that several crudely drawn ISIS style flags of tawheed were painted on a nearby wall shortly before the attack. It is unclear if ISIS will claim responsibility for the attack. Witnesses said that the five blasts went off in the space of 15 mins, at around 6:30am. It is thought the devices had been placed underneath the cars parked in front of their owners' homes.

Photographs of the animal IEDs emerged as the U.S.-led coalition battling ISIS dropped new leaflets over the terror group's de facto capital Raqqa, vowing to bring 'freedom' to those living there.

A Raqqa-based anti-Islamic State group and the Britain-based Syrian Observatory for Human Rights said the leaflets had drawings showing dead extremists and their flag turned upside down.

Four fighters with the main Kurdish militia, the People's Protection Units, or YPG, walked down a street in the picture, with words in Arab below: 'Freedom will come.'

The network called Raqqa is Being Silently Slaughtered posted a copy of the leaflets on its Twitter account. There was no immediate response from ISIS.

Coalition warplanes have dropped such leaflets in the past. One previous had a cartoon showing masked ISIS extremists at a 'hiring office' feeding people into a meat grinder.

ISIS holds about a third of Syria and neighboring Iraq in its self-declared 'caliphate.'

The latest leaflet drop comes as YPG fighters have been advancing in northern Syria as close as 30 miles north of Raqqa.

On Friday, a truck bombing by the group in Iraq's eastern Diyala province killed 115 people at a crowded market.
