Dutch Party For Freedom (PVV) leader and prominent counter-Islamist campaigner Geert Wilders has spoken exclusively to Breitbart London in the aftermath of this morning’s major terror attack and has lamented it is just the beginning of growing Islamist violence.

Mr. Wilders said: “I fear that we ain’t seen nothing yet. According to Europol 3,000 to 5,000 European jihadists, who went to Syria to fight in the ranks of IS and similar terrorist groups, have meanwhile returned to Western Europe. Some of them hid among the hundreds of thousands of Islamic asylum seekers that entered Europe from Asia and Africa.

“Two of last November’s terrorist in Paris had fought in Syria. So had the terrorist who, last August, attempted to attack the high speed train between Amsterdam and Paris. So had the two terrorists who, in January 2015, massacred the editorial staff of Charlie Hebdo. So had the terrorist who, in May 2014, shot four people at the Jewish Museum in Brussels”.

Belgian police have recently said at least 90 returned fighters from the Islamic State are living at liberty in Brussels, many of them in the infamous Molenbeek neighbourhood. European Commission insider Hermann Kelly told Breitbart Radio this morning he was concerned so many lived just miles from the political capital of the European Union.

Mr. Kelly said: “This is amazing to me that these people can kill people abroad, come here, and then walk free in the centre of Brussels”. On this, Mr. Wilders remarked: “Returned Syria fighters are a huge threat. They are dangerous predators roaming our streets. It is absolutely unbelievable that our governments allow them to return. And it is incredible that, once returned, they are not imprisoned.

“In the Netherlands, we have dozens of these returned jihadists. Our government allows most of them to freely walk our streets and refuses to lock them up. I demand that they be detained at once. Every government in the West, which refuses to do so, is a moral accessory if one of these monsters commits an atrocity.

“The government must also close our national borders. The European Union’s Schengen zone, where no border controls are allowed, is a catastrophe. The Belgian Moroccan Salah Abdeslam, the mastermind of last November’s bloodbath in Paris, travelled freely from Belgium to the Netherlands on multiple occasions last year.

“This is intolerable. Open borders are a huge safety risk. Our citizens are in mortal danger if we do not restore control over our own national borders”.

Speaking earlier today Mr. Wilders lamented that commuters were killed in “cold blood” and said “The cause of all this bloodshed is Islam. We need to de-Islamize the West. That is the only way to safeguard our lives and protect our freedom”.
