An explosion in a warehouse in Myanmar\'s capital early Thursday killed at least 10 people and left dozens injured, authorities said. The 2 a.m. blast in Yangon was big enough to be heard miles away, China\'s official Xinhua news agency reported. The cause of the explosion, which ignited a blaze that firefighters brought under control, had not been determined. More than 50 people sustained injuries and emergency officials arranged for two nearby schools to be used as shelters for people who were displaced by the explosion.
