The Islamic State (ISIS) is building squadrons of armed drones that the terrorist group plans to use to carry out devastating terror attacks, military sources have revealed.
The sources told the Daily Express that the jihadis have already been using these drones to co-ordinate fighting in Syria and Iraq since they declared a caliphate in June 2014.
As proof, the slick propaganda videos released by ISIS have been shot using video cameras attached to these unmanned flying machines.
The sources said they recently found out that ISIS is in the "final stages" of testing armed versions of these drones for use in terrorist attacks.
Last week, Iraqi militias reportedly spotted drones over Fallujah and Haditha, cities still occupied by ISIS forces.
The drones are fitted with cameras and could cover at least 42 miles, intelligence sources said.
They said they received information that the drones are being assembled in industrial plants outside the occupied Iraqi city of Mosul.
Last year, rumours circulated that ISIS terrorists were plotting to use drones to target major events such as football matches and music events in Britain.
"They want the spectacular devastation of such a raid, which would cause murder and maiming in a crowd, while filming it for a sick video," a British counter-terrorism official said.
"ISIS is obsessed with re-creating the horror of 9/11 and believes this may be possible by launching a multi-drone attack on large numbers of people in a synchronised attack."
Earlier this month, the Oxford Research Group came out with a report describing drones as a "game changer in the wrong hands."
It said the drones could be turned into "explosive devices" and used to attack the British Prime Minister David Cameron himself as well as foreign embassies.
Chris Abbott, lead author of the report, said: "The technology of remote-control warfare is impossible to control."
