BANJA LUKA, Bosnia-Herzegovina (AP) - Bosnian authorities say a mosque caught fire in a Serb-controlled town in Bosnia hours before local Muslims were to hold a holiday mass in it.

Police spokeswoman Rajna Parezanin says no one was injured but there was much damage. She says police are not yet able to say what caused the fire.

The issue is sensitive because Monday is the start of Eid al-Adha, the most important holiday in the Muslim calendar. Also, the mosque is in the southeast town of Fazlagica Kula, where Christian Orthodox Serbs expelled Muslim Bosniaks during Bosnia’s 1992-95 war. Part of the Muslim population returned after the war, but was often attacked - once in 1999 with mortars.
