A British ISIS fighter poses gleefully in front of a decapitated soldier strung up and murdered in Syria.

Abu Abdullah Al-Habashi, 20, who fled the UK for the Middle East nine months ago, has ‘no sympathy’ for the executed man and said ‘people love to see heads on spikes’.

The Muslim convert is among the hundreds of people who have fled to UK to fight in ISIS and says ‘there is no going back’.

Up to 500 British Muslims are believed to be in the region with as many as half joining forces with ISIS, a group known for its extreme violence, including crucifying and beheading its enemies.

Justifying the gruesome photo the British citizen originally from Eritrea told BBC’s Newsnight: ‘People love to see heads on spikes.

I feel no sympathy for them because they are all enemies of Allah.
