ISIS barbarians decapitate five 'spies' and stick their heads on SPIKES in latest brutal execution video

ISIS fanatics have beheaded five 'spies' before sticking their heads on spikes in the terror group's latest sickening execution video. Gruesome footage shows men in orange suits kneeling in front of masked ISIS extremists near the town of Al-Bokamal in the eastern countryside of Deir Ezzor, Syria.

Dressed in black and carrying hunting knives, the executioners issue a series of chilling warnings to their enemies, before
throwing the prisoners to the floor.

They are each then decapitated before their heads are left on metal pegs and their bodies abandoned in the desert.

According to the The Syrian Observatory for Human Rights (SOHR), the men were accused of working for US-backed New Syrian Army (NSA) and 'crusade forces'.

The five young men, all arrested in Al-Bokamal, had been accused of spying for NSA, which has recently advanced on key ISIS supply lines between Syria and Iraq.

According to SOHR, one of the executioners warned spies that 'our bayonets are hungry for your blood'.

The observatory named the men as Asim Hammam al-Debs, Harith Ahmad Jalid, Muhannad Ahmad al-Mshawwah, Abdul Rahman Ahmad al-Ashaab and Mohannad Obaid Al-Hussein.

The video purportedly shows them admitting to their 'crimes' and how they gathered and then communicated information.

Meanwhile, ISIS claims to have killed 40 US-backed fighters during a deadly counter-attack as the terror group recaptured a Syrian airbase.  

The New Syria Army rebel group had launched an operation on Tuesday aimed at capturing the ISIS-held border town of Al-Bukamal from the terror group.

But one rebel described how ISIS fighters had since encircled their fighters in a surprise ambush, inflicting heavy casualties, taking prisoners and seizing their weapons.

ISIS affiliated Amaq news agency had earlier said it had killed 40 rebel fighters and captured 15 more in a counter-attack at the Hamadan air base north west of the city. 

A rebel source said: 'The news is not good. I can say our troops were trapped and suffered many casualties and several fighters were captured and even weapons were taken.'

A spokesman of the New Syria Army, Muzahem al Saloum, confirmed the group's fighters had retreated. 

'We have withdrawn to the outlying desert and the first stage of the campaign has ended,' Saloum told Reuters.
