Rescue workers in New Zealand are still trying hard to find miracle survivors through the debris in quake-hit Christchurch. As many as 76 people are confirmed dead after Tuesday's 6.5 earthquake that devastated Christchurch. Police said 238 were missing and a further 164 people have been hospitalised with injuries ranging from major crash, head and neck and spinal trauma, and broken bones. As aftershocks continue to rock the city, New Zealand Prime Minister John Key, who declared a state of national emergency yesterday, conceded it would take a miracle to find more survivors. Meanwhile, the US President Barack Obama today offered all help in rescue and relief operations as he called New Zealand Prime Minister John Key to offer condolences over the devastating earthquake that struck Christchurch. During the telephonic conversation, Obama noted that a US search and rescue team was on its way to New Zealand, and said the US was ready to provide whatever further support was needed in this difficult time.
