Trapped Chilean miners 'could be free in two months'

Engineers in Chile are working on a plan that they hope will dramatically speed up the rescue of 33 miners trapped in a collapsed shaft.

Workers are due on Monday to start drilling an escape shaft going about 700m (2,300ft) underground, which is likely to take four months to complete.

But engineers say widening an existing tunnel may reach the men in two months.
