A reporter for the Associated Press found identity cards from an array of nations dumped along the Serbia-Hungary border. Those included Pakistani and Bangladeshi identity cards and an Iraqi driver’s license.

A border police officer told the AP that there’s even more reason to suspect some nationality claims are “fishy.”

“You can see that something is fishy when most of those who cross into Serbia enter January first as the date of their birth,” border police officer Miroslav Jovic told the AP. “Guess that’s the first date that comes to their mind.”

The New Zealand Herald on Monday called the revelations “The big migrant passport scam.”
