17-year old Briton IS's youngest suicide bomber

A 17-year old who left northern England to join Islamic State was reported to have become Britain's youngest suicide bomber when he blew himself up in a car in northern Iraq, British media said after the militants posted pictures on social media.

The young man, who was named as Abu Yusuf al-Britani, was shown standing next to a black vehicle in photographs posted on Islamic State-affiliated social media accounts, the Guardian newspaper reported. The posts said he then took part in a suicide attack in Iraq's Salahuddin province.

He is believed to be Talha Asmal, a teenager who left West Yorkshire in March, and was thought to have joined Islamic State, according to a statement from his family.

"Although the information within these reports has not been confirmed and the relevant UK authorities are working hard to verify the facts, we can confirm that the photographs shown of a youth purportedly named Abu Yusuf al-Britani appears to show our 17-year-old son Talha," the family of Talha Asmal said in a statement issued by West Yorkshire police on Sunday.

"We are all naturally utterly devastated and heartbroken by the unspeakable tragedy that now appears to have befallen us," they added.

Security services have estimated that at least 600 Britons have gone to Syria or Iraq to join militant groups, including the man known as "Jihadi John" who has appeared in several Islamic State beheading videos.
