Islamic State fighters have beheaded a group of soldiers captured during a night time offensive on a military airbase, while a new propaganda video purports to show the jihadis shooting down a fighter jet during a skirmish with Syrian forces.

Islamic State (ISIS) fighters carried out a night time attack on an airbase near the Syrian city of Deir ez-Zor, capturing several Assad soldiers and beheading them while photographing the event and posting the images online.

It comes amid the release of yet another ISIS propaganda video, purporting to show the militants shooting down a fighter jet using an anti-aircraft gun.

Following the attack on the military airport, ISIS militants rounded up a number of Syrian army prisoners. Photos have emerged showing one of the fighters begging for his life.

Still wearing his camouflage fatigues, the fighter appears to be crying as several ISIS fighters surround him. One of the fighters wearing a pair of leather gloves can be seen holding the terrified prisoner down by the collar of his neck.
