ISIL playboy's widow posts 'catch me if you can' taunt

A Melbourne woman who fled to Syria to marry a playboy Islamic State fighter has remained defiant after her husband's death, telling authorities to "catch me if you can".

Zehra Duman, 21, posted the taunt on her social media account beside an image of a woman holding an assault rifle, with a knife at her feet, News Corp reports.

Duman also posted new photos of husband Mahmoud Abdullatif, 23, who was reportedly killed while fighting with ISIL last weekend.

The photos show Abdullatif standing on a roadside covered in snow, holding up a weapon.

"A few days before he attained shahadah. Was so excited to see the snow! Lol. Oh how I miss you, may Allah reunite us," the post reads.

Duman, thought to be based in Raqqa, is among up to 30 Australian women who have travelled to Syria either to join their terrorist partners or marry ISIL fighters.
