Islamic State militants have called on supporters across the world to stage attacks in their defence, according to a newly released audio recording.
The recording, purportedly from IS, came as the Kurdish-led Syrian Democratic Forces faced continued resistance from IS gunmen as US-backed fighters try to push deeper into the village of Baghouz on the eastern bank of the Euphrates River.
The brief, minute-and-a-half recording, released by IS supporters on social media and reported by the SITE Intelligence Group, said that men, women and children in Baghouz are being subjected to a "holocaust by the Crusaders".
On the ground, commanders said they have been hindered by IS sniper fire, but are relying more on air strikes and heavy weaponry, rather than ground forces.
Argish al-Deiri, an SDF commander in Baghouz, on Tuesday said IS militants had been fighting back with heavy weapons, rifles and sniper fire, forcing SDF fighters to slow their advance rather than advancing quickly so that "you don't lose your men".
He said he hoped the IS fighters will surrender in the coming "few days".
