Chile mine rescue drill being assembled steadily

Parts of a massive drill needed to rescue 33 miners trapped in a Chilean mine have been arriving at the San Jose mine in Copiapo.

The plan is to bore a narrow shaft down to the men, some 700m (2,300ft) underground, then widen it so they can be brought to the surface one by one.

The engineer in charge of the operation has said it could take up to four months to free the miners.

Gideon Long reports from Copiapo.
