An image of a baby about to be beheaded by an Isis (Islamic State) militant has been recovered from a mobile phone.

The picture is among several recovered by Kurdish soldiers from the mobile phones of dead fanatics in the besieged Syrian town of Kobane.

The image shows the distressed baby girl being pinned to the floor, as a knife is held to her throat.

The child is believed to be from a family of Alevi Muslims, a branch of Islam whose followers have been targeted by Isis.

A source who reportedly obtained the picture from YPH soldiers, was quoted by the Mail on Sunday as saying: "Each time I look at this picture it makes me weep. You can see how frightened she is.

"I can almost hear her scream. What kind of depraved monsters are they? What pleasure can killing this child bring anyone?"

Highlighting the brutality of the terror group, fighters have circulated the picture on Facebook nicknaming the baby 'Melek', meaning angel.

"The people of Kobane are desperate for the world to see with their own eyes the atrocities inflicted by these filth," he added.

According to eye witnesses the baby, a woman and an older child were witnessed being dragged out of hiding by Isis around the time of an air strike. There were no shots of her decapitation and her body has not been found, fuelling hopes that the child and her family might yet be safe.

"Some have a flicker of hope in their hearts that they might have escaped," said Ali.

Other recovered images showed beheadings and jihadis playing football with the severed heads of victims

US airstrikes continue to hit Kobane where more than 1,100 people are thought to have been killed since last month.

Earlier, Isis militants released images of the public crucifixion of a teenage boy. The barbaric punishment took place over three days in the central square of the extremists' de facto capital Raqqa. The militant group accused the teenager of taking photographs of the terror group's headquarters in Syria.
