New Zealand Prime Minister John Key today declared a state of national emergency following the devastating earthquake that led to massive buildings collapsing in Christchurch. So far death toll has reached 75. Media reports said around 55 bodies had been identified. 20 bodies are yet to be identified. Another 300 people were listed as missing, though not all of them would be trapped in buildings that were being searched for survivors. Superintendent Russell Gibson said bodies still littered the streets. Gibson added that the toll would rise significantly. Overall, 120 people have been pulled alive from the rubble. More than 500 rescuers, including police and military personnel, pulled between 20 and 30 people from the debris overnight.
