The Islamic State in Iraq and Syria (ISIS) has reportedly used makeshift chemical projectiles against Kurdish militia in the far north-eastern city of Hasakah.
The attacks have been documented by both the Conflict Armament Research (CAR) and Sahan Research.
According to the two institutions, ISIS used homegrown poison gas projectiles to attack Kurdish fighters’ positions in Hasakah and Tal Brak in June.
Urine tests made for those attacked in Tal Brak proved positive for an agent commonly used in manufacturing agricultural pesticides. None of the affected Kurdish fighters was killed since they received the necessary medical care immediately after the attack.
A similar attack has been carried out against Iraqi Peshmerga fighters earlier on the 21st and 22nd of June.
The western-backed Kurdish fighters in Syria and Iraq are fighting the hardline group in cooperation and coordination with the US-led coalition.
In their failed bid to take over the northern Kurdish stronghold of Kobani in 2014, ISIS allegedly used mustard gas against Kurdish militia.
