Chile requests international aid in rescue of copper miners
None
With time running out for 33 miners trapped deep inside a gold and copper mine, Chile's president is pleading for international help.
The miners have now been trapped more than 800 yards below the surface for four days since the main access collapsed with tons of falling rock. Rescuers were working around the clock to reach the miners through a narrow air shaft, but on Saturday it, too, collapsed. (AP)
