Residents of Gaoqiao, a town in Southwest China's Chongqing Municipality, watch the raging flames of a gas leak on Saturday night March 25, 2006 as they leave their homes. A blast at a gas well on Saturday morning forced the evacuation of more than 11,500 local residents. No casualties had been reported by press time. The accident took place in the same area as a leak in December 2003, which caused the deaths of 243 people. [Xinhua]
