"…Evidently, the refugees include those who were fighters from the armed terrorist groups, such as the Islamic State and the Al-Nusra Front. How can we know who these people are if we, namely, the Western European countries, stopped cooperating with the Syrian security services?" Blanchard said.
As an example, he referred to the situation in Serbia, where police arrested several dozen terrorists as a result of a close interaction with the Syrian police.
Also, Blanchard urged France to cooperate with Russia as far as the fight against the Islamic State is concerned. He praised "Russia's ever-increasing efforts to support Syria combating Islamic State militants."
"I think that if Francois Hollande wanted to be consistent and sought to put an end to the flow of refugees to Europe, he should welcome Russia's support in the fight against the Islamic State and other terrorist groups," Blanchard said.
Additionally, he called on EU countries and the United States to do their best to support the UN agencies delivering humanitarian aid to the refugee camps in Turkey.
"2016 will see the beginning of a huge reduction in aid, and if there is no mobilization of the European countries, the outcome will be even bigger, because people will not be able to remain in the camps without food, water and a roof over their heads," Blanchard warned.
On Friday, Croatian Prime Minister Zoran Milanovic said that the country was no longer capable of registering and housing all the refugees arriving there, and therefore decided to start sending them to its external borders by bus.
Hungarian Foreign Minister Peter Szijjarto has, for his part, condemned Croatia for inciting refugees to break a law by illegally crossing the Hungarian border.
