The self-proclaimed Islamic State [Daesh] has released a propaganda video threatening Turkey,describing its president as an “infidel” and a “traitor”.

The men featured in the video, believed to be ISIL militants, urge Muslims in Turkey to support the extremist group.

The video was uploaded onto a social media website and is believed by Reuters to be genuine.

The militants accuse President Erdogan of opening up Turkish airbases to “crusaders”, allowing the US to “bombard the people of Islam”.

Six F-16 fighter jets arrived at a Turkish base last week and began flying missions against ISIL over Syria.
