Chile miner rescue 'to take four months'
It will take at least four months to rescue 33 miners trapped underground in Chile, the head of the rescue operation has said.
Rescuers made contact with the miners by lowering a probe into the mine, 17 days after the men became trapped.
The miners, stuck in a mine shaft shelter some 700m (2,300ft) down, sent up a note saying they were all alive.
Rescuers are now preparing to drill a wider hole through which they can bring the miners to the surface.
