Children killed in Burma school fire "According to the investigation by township police officers, the fire was caused by excessively high (electric) voltage," it added. Police officer Thet Lwin said the mosque sheltered about 75 orphans, and most escaped unharmed by running out of a door after police knocked it open. A wave of sectarian violence that began on March 20 has left 43 people dead and mosques and homes burned in several towns in central Burma, prompting the government to impose emergency rule and curfews in some areas. The situation in Rangoon has also been tense, but mostly peaceful. Edited by Bonnie Malkin
