Shocking moment ISIS assassins murder a 'military chief' in Yemen

This is the shocking moment ISIS assassins murdered a military chief in Yemen in a gangland-style drive-by shooting. Pictures show a fanatic pointing a gun with a silencer
attachment out of the window of a car before shooting a man in the back of the head in the war-torn city of Aden, Yemen.

The victim, dressed in white, falls to the ground before the gunman fires another shot.

ISIS militants claim the images show the assassination of a colonel - though this has not yet been verified.- Daily Mail
