The dreaded Islamic State terror group has released sickening videos showing how hostages are executed with explosive necklaces and rocket launchers.
The Islamic State has released a series of sickening execution videos purportedly showing rebels being slaughtered by rocket launchers, explosive necklaces and blown up at sea.
The footage opens with scenes of warfare in Yemen before six alleged Houthi rebels in orange jumpsuits are forced to march to a rocky hillside.
They are then fired at by what is apparently a Katyusha rocket launcher, detonated remotely, and blowing them to pieces.
Another group of Houthi rebels were seen being led onto a boat in single file and wearing shackles before it is pushed into the sea.
Moments later the boat explodes, killing the six men on board.
The terrorist organisation, which has territory in Syria , Iraq and Libya, has spread to Yemen in recent months as the country fights its brutal ongoing sectarian war.
This video is believed to be the third released by the extremist group in the first few days of December.
