Last ISIS enclave in Syria about to fall

Kurdish-led forces in Northern Syria have stepped up the assault on the last enclave held by Islamic State fighters. With US airstrikes and intense fighting on the ground they are edging closer to ending the self-declared caliphate.

The Syrian Democratic Forces say they have killed dozens of ISIS fighters and captured a weapons depot, but there are still fears for civilians, including an unknown number of missing Yazidis who may be trapped behind the front line.
