The Kurdish-led Syrian Democratic Forces (SDF) say their spy stole Abu Bakr al-Baghdadi’s underwear which was then DNA tested and used to prove his identity before he was killed.

Senior SDF commander Polat Can claims their source also played a vital role in tracking down the Islamic State (IS) leader’s location before an operation by US special forces in Syria.

Baghdadi killed himself in the raid.

US President Donald Trump has downplayed the role of Kurdish forces.
