New Zealand's Prime Minister John Key says at least sixty five people have died after a 6.3-magnitude earthquake struck Christchurch on South Island. The tremor, which hit only ten kilometers south-east of the city at a depth of five kilometers, caused widespread destruction. The fire service said numerous people were trapped in buildings, and a state of emergency has been declared. The damage is said to be far worse than after September's 7.1-magnitude quake.
