Bosnian authorities said on Monday that a mosque caught fire in a Serb-controlled town in Bosnia hours before local Muslims were to hold a holiday service in it. Police spokeswoman Rajna Parezanin said that no one was injured but there was much damage. She said that police were not yet able to say what caused the fire. The incident comes at 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.
