Kosovo police say they have foiled an apparent attempt to detonate a car filled with explosive material in the capital Pristina.

Police spokesman Baki Kelani said the driver of the car has been arrested and questioned. He said police acted on intelligence and stopped the suspect late Thursday as he drove toward an area where most Western embassies are located, including the United States Embassy.

Kelani said the car had Serbia-issued license plates and that the driver has a Serbian passport, but did not disclose his ethnicity or religion.

Kosovo's ethnic Albanians are overwhelmingly Muslim. Authorities have warned of a potential backlash from Islamic radicals after dozens of them were arrested earlier in the year upon suspicion of fighting alongside extremists in Syria and Iraq.
