The chilling first person clip shows Colonel Abd Al-Rahim Al-Dale'i being gunned down at point blank range
Sickening video game-style footage of an ISIS militant executing a Yemeni colonel has been released online.
The chilling first person clip shows Colonel Abd Al-Rahim Al-Dale'i being gunned down at point blank range by a masked assassin in the war-torn city of Aden, in Yemen.
The airport security boss is seen getting into his car when he is approached by the militants.
Harrowing footage shows the ISIS fighter point his weapon at Mr Al-Dale'i before pulling the trigger.
The graphic video then shows the victim lying sprawled on the ground, his checked shirt spattered with blood.
No group initially claimed responsibility for the execution, however ISIS later released footage of the attack.
It comes as a Yemeni man living in New York City was arrested and charged on Monday with attempting to provide support to ISIS.
Mohammed Rafik Naji travelled to Turkey and Yemen in an effort to join the militant group last year, authorities said.
The 37-year-old is believed to have expressed support for a terror attack in Times Square.
Naji is one of more than 100 people to face US charges since 2014 in cases related to the Islamic State militant group, which has seized control of parts of Iraq and Syria.
