A Mexican blogger has released an message purportedly sent by infamous cartel boss Joaquín Guzmán to Islamic State (Isis) leader Abu Bakr Al Baghdadi via encrypted email. Guzmán is the head of the international Sinaloa cartel and is perhaps better known as 'El Chapo'.

Guzmán is currently on the run after escaping from maximum security prison in Mexico for a second time in July. His Sinola cartel is one of the biggest in the world, with operations in five continents. Guzmán was at one time included on the Forbes list of billionaires.

Daesh (IS) fighters have allegedly been destroying Sinaloa shipments, angering the cartel and its elusive leader.

According to cartelblog.com, the leaked email said: "You [ISIS] are not soldiers. You are nothing but lowly p*ssies. Your god cannot save you from the true terror that my men will levy at you if you continue to impact my operation.

"My men will destroy you. The world is not yours to dictate. I pity the next son of a wh*re that tries to interfere with the business of the Sinaloa Cartel. I will have their heart and tongue torn from them."

Though drugs are strictly prohibited by IS, there have been suggestions that they are involved in the trade of fake Captagon tablets in the Middle East.

Baghdadi is similarly elusive, rarely making public appearances, though Time magazine recently declared him runner-up person of the year 2015 behind German chancellor Angela Merkel.
