Amaq News, which acts as a semi-official news agency for the ISIS has released a new video showing a drone striking an Iraqi tank from the air.

The footage, which cannot be independently verified as of publication, proves increasing fears of ISIS’ growing sophistication in modern warfare.

The attack reportedly took place in an unknown location near Mosul, where an ongoing operation to retake the city from ISIS is entering its fifth month.

Special forces Lt. Gen. Abdul-Wahab al-Saadi said on Saturday that his troops are “moving very slowly” and that ISIS fighters are responding with car bombs, snipers and dozens of armed drones.

The drones have caused relatively few deaths, but have inflicted dozens of light injuries that have disrupted the pace of ground operations.
