PRISTINA, Kosovo (AP) — Kosovo police say they have arrested 15 people suspected of links with Islamic radicals, including Muslim clerics and a politician.

Police said in a statement on Wednesday the suspects pose a threat to Kosovo's "national security" and that they seized material believed to link them with religious extremists. Police didn't identify the suspects.

Wednesday's sweep follows two similar operations since mid-August. Last month, 40 people were arrested in a major operation targeting Islamic radicals suspected of fighting In Iraq and Syria alongside the Islamic State group. Kosovo is secular but its majority ethnic Albanians are overwhelmingly Muslim.
