ISIS-linked militants have used a booby-trapped drone for the first time to attack Kurdish and French troops in Iraq, according to French media.
The attack took place on 2 October, near the Kurdish province of Erbil, killed two Kurdish Peshmerga fighters and inured two French soldiers, Le Monde reported on Tuesday.
An improvised explosive device (IED) has been used in the drone.
No group has claimed responsibility for the attack, however, Le Monde reported that it had links to ISIS.
The two French soldiers who sustained severe injuries were evacuated to a military hospital just outside Paris.
More than 10 other French soldiers who were also injured were reportedly evacuated.
The French troops have been fighting alongside Kurdish Peshmerga forces in the combat against ISIS around Erbil for more than two years.
Armed groups inside Iraq and Syria have long been using drones for surveillance, but has not been using the drones as weapons in themselves.
The US has ordered its troops to take cover when they identify an aerial vehicle that might be linked to terrorists.
Pentagon announced months ago that it is spending $20 mn into developing counter-drone technology to meet threats from ISIS.
It has already been using the Batelle Dronedefender, which targets and jams the radio signals that control drones, and is working on laser weapons that have been designed to shoot drones out of the sky.
