Tuesday's unrest in Lashio was sparked by a quarrel between two people, named by state media as Aye Aye Win, 24, a Buddhist woman who sold petrol, and Ne Win, a Muslim man aged 48. MRTV television said Ne Win poured petrol over Aye Aye Win and set her on fire. She was in hospital, it said. After police detained Ne Win, Buddhists surrounded the police station and demanded he be handed over. When they refused, the crowd went on the rampage, attacking Myoma Mosque near Lashio market, residents said.
