A fire ripped through a two-story warehouse Tuesday in central China's Wuhan city, killing 12 people, including three children. The blaze, which is believed to have been triggered by a short circuit in an electrical outlet on the warehouse's first floor, started at about 9:25 a.m., Xinhua quoted a spokesman from the city's firefighting department as saying. It took approximately 170 firefighters almost two hours to put out the fire, the spokesman said. Although most of the people in the warehouse managed to flee the warehouse after the fire broke out, several of them became trapped on the second floor. An investigation into the cause of the fire is under way.
