The President of Chile Michelle Bachelet says that the number of people confirmed dead after Chile's earthquake has soared to 708 and is expected to rise further. Previously about 300 people had been reported to have been killed in Saturday's 8.8 magnitude quake, one of the most powerful recorded. Massive damage is hampering rescue teams as they struggle to reach those still buried in the rubble. The Chilean government has declared a curfew in two of the worst-hit areas. State television reported that the curfew would apply in the regions of Maule and Concepcion. The army is being sent to support police to prevent unrest in Concepcion.The mayor of Concepcion city has said food is running out and police used tear gas and water cannon against looters at a supermarket yesterday. Rescue teams are still trying to reach dozens of people believed to be trapped in a collapsed block of flats in Concepcion. Many Chileans in affected areas have spent the first night since the earthquake outdoors afraid to stay inside. Speaking to reporters yesterday, the President Ms Bachelet said the catastrophe is enormous. She said 541 had died in Maule region, 64 in Biobio and a total of 103 in other areas.
