No Go Zones are a persistent and growing problem in Europe and are coming to the United States, Breitbart London Editor in Chief Raheem Kassam said Monday as his new book No Go Zones: How Sharia Law Is Coming to a Neighborhood Near You was released.

Speaking as a guest on the Laura Ingraham Show, Kassam said he had travelled to a number of No Go Zones in the course of the research for his book and found that the United States was now following a path that Europe was already a decade or more advanced in, leading to areas of Western cities being written off to extremist groups.

Explaining his rationale to the show host, Kassam said: “This is the only book of its kind, I’m stressing that at the moment because that’s what made me write it. I explored on foot, personally, a lot of these areas across Europe, and indeed areas in the United States that are starting to look very similar. Places that have basically fallen to Muslim mass migration.”

Fleshing out how this same pattern was being seen now in America, Kassam remarked: “When I went to Hamtramck in Michigan I saw very much the same sort of thing going on there that was going on in Molenbeek 15, 20 years ago… there are warning signs.

“A city like Hamtramck is 2.1 square miles, and the bottom estimate says there are 12 mosques there, and the upper says there are 17 there… that’s about a mosque every other, or every third street corner. The city council is now majority Muslim, the call to prayer is played from the mosques onto the streets… that’s just one of the warning signs.”

Pointing to other such signs, Kassam singled out the “prevalence of Halal food” and its links to funding terror organisations, and the veiling of women as a clear sign of oppression growing in Western societies.

Speaking of his experiences in European No Go Zones, Kassam, who could clearly be heard smoking while speaking to the show host, recounted one episode that did not make it into the book. He said: “I went to Tower Hamlets in East London just a couple of weeks ago, actually after I concluded the book, during the UK election.

“There was a group of men who came up to me, and they said you’ve got to leave this area if you’re not voting Labour.”

Apologising that he would not repeat the actual phrases directed towards him during the encounter because there might be young listeners tuned in, Kassam continued: “There was graffiti on the shutters on the stores that said ‘Taliban are here’; this is 2017, and these are Western countries. This is what we’re seeing, and, unfortunately, it isn’t unique to Europe. It’s coming here too.”

Kassam’s No Go Zones, which hit a number of Amazon bestseller categories weeks before release and has continued to climb the ratings since release on Monday is published by Regnery and is available now on Amazon.com (and Kindle), Books-a-Million, Barnes & Noble, iTunes, and Audible.
