US-backed Syrian troops taunted defeated ISIS fighters with techno pop as the ‘caliphate’ finally fell after a six-week siege

Defeated Islamic State fighters were blasted with booming techno music as their shattered final stronghold of Baghuz fell.

After a six-week siege, coalition forces stormed the final 700 square metres of the so-called caliphate, which four years ago ruled an area the size of England.

In a desperate last stand, hardened IS fighters thrust weapons into the hands of their wives and daughters, but they were helpless to protect territory reduced to a sea of rubble and twisted metal against a merciless bombardment.
