A market in fake Syrian passports has sprung up, particularly in Turkey, to help migrants and refugees enter the EU, the head of Europe's border agency Frontex said on Tuesday, according to AFP.

"There are people who are in Turkey now who buy fake Syrian passports because they know Syrians get the right to asylum in all the member states of the European Union," Fabrice Leggeri told French radio station Europe 1.

"People who use fake Syrian passports often speak Arabic. They may come from North Africa or the Middle East but they have the profile of economic migrants," he said. Leggeri said there was no evidence that fake passports had been used by potential terrorists to enter Europe.
