The Islamic State of Iraq and Syria (ISIS) has threatened the world claiming they are very close to acquiring a nuclear bomb from Pakistan to use in attacking the United States.

The claim was made in an article entitled "The Perfect Storm" which was published in the Islamic State's English language propaganda magazine Dabiq; it was penned by British hostage John Cantlie, The Telegraph reported. 

Cantlie, a photojournalist, has been kept hostage by the Islamic State for more than two years. He is regularly seen in Islamic terror propaganda videos, including in a YouTube series called "Lend Me Your Ears." 

 "The Islamic State has billions of dollars in the bank, so they can call on their wilāyah in Pakistan to purchase a nuclear device through weapons dealers with links to corrupt officials in the region," the article states, according to The Independent.

"The Islamic State makes no secret of the fact they have every intention of attacking America on its home soil and they're not going to mince about with two mujāhidīn (jihadis) taking down a dozen casualties if it originates from the caliphate," the article further said, according to MailOnline.

The Islamic State, also known as ISIS/ISIL/Daesh, has outlined its plan to move the hypothetical nuke weapon to carry out an attack on the United States.

"The nuke and accompanying mujahidin arrive on the shorelines of South America and are transported through the porous borders of Central America before arriving in Mexico and up to the border with the United States. From there it's just a quick hop through a smuggling tunnel and – hey, presto, they're mingling with another 12 million "illegal" aliens in America with a nuclear bomb in the trunk of their car," the chilling article reads, according to IANS.
