Death by explosive necklace, rocket launcher, or obliterated at sea: ISIS release a series of sickening execution videos from war-torn Yemen filmed in just 24 hours

Barbaric: In another sickening execution video, six men sitting on a rocky hill were blown up by a rocket launcher

The videos, all shared by ISIS supporters today, come a day after the UK’s first airstrikes on Syria, where ISIS controls large swathes of territory.

ISIS, who also have territory in Iraq and Libya, have been able to spread to Yemen in the midst of its own civil war.

Last month, the terror group claimed to be behind the synchronised attacks that killed at least 15 and wounded 30 at checkpoints manned by troops loyal to Yemen’s internationally recognised government.

The Houthis are a Sunni Muslim group that has been battling AQAP. ISIS, who claim to be a Sunni group, see them as ‘apostates’ – or those who have abandoned Islam.

Attacks by pro-ISIS groups intensified in October after they pledged allegiance to the group’s leader Abu Bakr al-Baghdadi.

These extremist groups were said to be operating out of the capital Sana’a and other cities along the country’s south and south-east.

Death at sea: Another group of at least six men were put on a boat and pushed out to sea by ISIS fanatics

Gruesome: The boat was then remotely detonated, sending huge shards of the vessel and the men on board exploding into the air

Execution: At least nine men were made to kneel on the ground before they were beheaded by ISIS terrorists in another propaganda video

These factions attacked both government soldiers and those they described as Shi’ite – mostly the Iranian backed Houthis.

Al Qaeda’s branch in Yemen today put a bounty on the head of a pro-government force in the south as it seeks to impose itself as the dominant force in the conflict.

It circulated a statement during weekly prayers in Yemen’s mosques in which it vowed to kill Abdellatif al Sayed, a commander of the Popular Resistance – an alliance of Sunni Islamists, tribesmen and government troops.
