A recent trend amongst terrorists in the Middle East has been to equip off-the-shelf drones with rudimentary explosives to turn them into miniature bombers. But the world’s largest drone manufacturer is fighting back.

Last year, the Pentagon announced that ISIS fighters had decided to add a weapon to its arsenal that America has been employing to devastating effect for years: drones. But instead of expensive, missile-carrying aircraft, the group's soldiers have begun using modified consumer drones that were retrofitted with explosives, turning them into flying bombs, or the means to to drop explosives on a target. This year, the terror organization even announced that it had established an Unmanned Aircraft of the Mujahideen unit, which claimed to have killed or wounded 39 Iraqi soldiers in one week using drones.

Now, the Chinese drone manufacturer DJI has decided to fight back, according to the Register. Software in the company’s drones can define no-fly zones that the aircraft are forbidden from entering. Typically, this geo-fencing technique is used them to prevent people from flying their craft into restricted areas, like airports and military bases. But DJI now appears to have added a series of locations across Syria and Iraq to the list, including the city of Mosul.
