US-backed Kurdish fighters battling ISIS in Syria released a video on Saturday showing them destroying a tank being used by Turkish-backed rebels in northwest Syria, Military Times first reported.

“Today at about 9:30 am our forces targeted and destroyed a tank belonging to terrorist groups under the Turkish army’s command near Azaz hospital in Afrin’s Shera district,” the YPG said on Facebook.

The video shows YPG fighters lying a concrete platform and then firing an anti-tank missile at the tank. The amount of damage or number of casualties is unknown.

Turkey views the YPG as a terrorist group and an extension of the PKK, which has been trying to set up its own Kurdish state within Turkey for decades.
