World's biggest drug kingpin El Chapo declares war on ISIS with chilling threat

One of the world's most wanted drug lords has reportedly 'declared war' on the Islamic State in a threatening letter. Joaquín “El Chapo” Guzmán apparently sent an encrypted email to the ISIS leader Abu Bakr Al Baghdadi after one of his cartel's shipments was destroyed. His letter, which has been leaked by cartelblog.com, claims his men will "destroy" the terror group if they continue to 'impact on their operation'.

The Mexican drug baron, who runs the notorious Sinaloa cartel, allegedly told Al Baghdadi that his organisation are 'not soldiers' but 'lowly p*****s'.

He apparently wrote: "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*** that tries to interfere with the business of the Sinaloa Cartel. I will have their heart and tongue torn from them, he wrote.

El Chapo, nicknamed "Shorty", has been on the run from police since he escaped from the maximum security Altiplano prison 55 miles west of Mexico City in July.
