Religious violence that saw mobs attack mosques and torch homes left at least one dead in central Myanmar, authorities said Wednesday, as anti-Muslim unrest crept closer to Yangon. Hundreds of police and troops then restored order.

Riots broke out Tuesday in the small town of Oakkan, around 100 kilometers north of Yangon, after a woman accidentally bumped into a young monk, authorities said, amid acute Buddhist-Muslim tensions after a series of attacks in March.

"A man died in hospital of his injuries this morning," a local police official told AFP, adding that nine others were injured.

Authorities have arrested 18 people after a series of arson attacks on Tuesday evening, president's spokesman Ye Htut said in a Facebook update, adding some 77 homes had been set alight in four villages in a region north of Yangon that saw a wave of conflict two months ago.

Terrified villagers of both faiths said police were not there to protect them when a crowd attacked a local mosque on Tuesday evening in Mie Laung Sakhan village.

"About 200 to 300 people arrived in our village on motorcycles and destroyed the mosque. All the villagers ran away. We were scared and didn't resist. They destroyed until they were satisfied," Soe Myint, 48, a Muslim, told AFP.

The village mosque was seriously damaged and around 10 homes burned, according to an AFP journalist at the scene. No security presence was visible until late morning, when about 30 police arrived.

"We heard rumors that the mob will come and attack again this afternoon. Even we were threatened to be killed. We are also scared. We need security urgently," Than Soe, a Buddhist, told AFP.

A heavy security presence was visible on Wednesday morning in Oakkan, where some 30 shops in the market had been destroyed and a mosque damaged.

Religious unrest has exposed deep fractures in Myanmar and cast a shadow over reforms under a quasi-civilian regime that took power two years ago.

At least 43 people were killed and thousands left homeless in March in fighting apparently triggered by a quarrel between a Muslim gold shop owner and Buddhist customers in the central town of Meiktila.
