Some interesting news from the investigation into the terrorist attacks in Paris: the Syrian passport found near one of the terrorists’ bodies may have been planted in an attempt to stir up anti-immigrant hatred in Europe.

“The single most intriguing fact is that the passport was there at all,” one French official source said. “It was not actually on the terrorist’s body, or what remained of it. It was lying nearby, as if meant to be found.” The holder of the passport was named as Ahmed Almuhamed, aged 25. A man of this name entered the European Union on a Syrian passport with 69 other refugees after their boat sank off the Greek island of Leros on 3 October.

The idea that one of the Paris “black Friday” terrorists may have been a recent Syrian refugee to the EU was seized upon gleefully by right-wing newspapers and politicians across Europe. The discovery appeared to substantiate claims that Isis terrorists have infiltrated the hundreds of thousands of refugees who have entered Europe this year.

French officials say that they have no proof that the Stade de France suicide bomber – one of three who detonated crude explosive belts at the stadium – was Mr Almuhamed. Intelligence sources in the US told CBS news that there are doubts whether the passport is authentic. The number of the document is incorrect and name does not match the picture, it was claimed.

Paris police were reported to have believed that the passport, and another found at the scene, were fakes made in Turkey. There is known to be a flourishing trade in fake Syrian passports in both Turkey and Europe. But that does not necessarily mean that the man who entered Greece as a refugee was not also the man who blew himself up.

French investigators fear that the apparent “planting” of the passport is part of a sophisticated propaganda war being waged by Isis. “There are three possibilities,” one source said. “He is the man whose name is on the passport. He was a false refugee, travelling on a false passport. Or he is someone else and a false passport was deliberately left there to sow confusion.”

In all three cases, Isis appears to have set out to stoke popular anger against Syrian migrants as part of their campaign to foment anti-Muslim feeling.

Right wing parties and media in Europe aren’t the only ones doing exactly what ISIS wants; here in the US, Republican governors are also dancing to the terrorists’ tune and rejecting Syrian refugees.

At least ten Republican governors are moving to block Syrian refugees from entering their states after Friday’s terrorist attacks in Paris that killed at least 130 people and wounded hundreds more.

Texas Gov. Greg Abbott, Massachusetts Gov. Charlie Baker, Indiana Gov. Mike Pence, Mississippi Gov. Phil Bryant, Illinois Gov. Bruce Rauner, Ohio Gov. John Kasich, Louisiana Gov. Bobby Jindal and Arkansas Gov. Asa Hutchinson on Monday joined Alabama Gov. Robert Bentley and Michigan Gov. Rick Snyder in refusing to accept refugees from Syria.
