Slovak's foreign minister says the flood of migrants crossing Europe could unite the far-right in his country, calling it a "scary" prospect.

In an interview with The Associated Press on Wednesday during a visit to Bucharest, Miroslav Lajcak said that "our society has no migration experience. There is a clear difference between the new member states and the old member states."

He said Western Europe was "multiracial" and "multi-religious", while there wasn't "a single mosque" in Slovakia.

Lajcak denied that Slovakia would select migrants based "on culture or religion." He said the far-right was "organizing demonstrations against migrants. They are scaring people."

He said migrants didn't want to settle in Slovakia, and that "they don't even know Slovakia exists at the beginning of their journey."
