The secretive 'Ninja' Hellfire missiles used to chop up Al-Qaeda leader Ayman al-Zawahiri were perfected in shadowy counter-terror operations in Syria, The Mirror can reveal.
US officers launched top secret drone attacks using the six-bladed R9X missiles against “many” terror targets at the height of their operations against ISIS.
Other key terror personnel signed up to al-Nusrah, an Al-Qaeda affiliate and rebel group were also targeted using the mince-maker Hellfires in joining CIA and special forces missions.
