Slovakia says it will only accept Christians when it takes in Syrian refugees under a EU relocation scheme.The country is due to receive 200 people from camps in Turkey, Italy and Greece under the EU plan to resettle 40,000 new arrivals.
Interior ministry spokesman Ivan Netik said Muslims would not be accepted because they would not feel at home.
The UN's refugee agency (UNHCR) called on countries to take an "inclusive approach" to relocation.
But Mr Netik denied the move was discriminatory and said it was intended to ensure community cohesion.
Note EU-Digest: whatever way the Slovaks want to call what they are doing - it is discrimination with a capital D and should be unacceptable by the EU.
