New Zealand mine explosion: 'The longer it goes on, hopes fade'
Police in New Zealand have admitted that hopes are fading of finding alive 29 miners, missing underground since an explosion on Friday.
The rescue operation has suffered a setback, when a remote-controlled robot broke down after being sent down into the Pike River Mine, on the country's South Island.
Police Superintendent Gary Knowles said experts still did not consider the air quality safe enough for rescuers to go underground to search for the men.
