Nasa doctor urges against 'false hopes' for Chile miners

A team of Nasa experts have arrived in Chile to aid the rescue of 33 miners and advised officials not to give them "false hopes".

The Nasa team, which includes a doctor, nutritionist, and engineer and a psychologist, arrived in Santiago after a request by the Chilean authorities. They are due to travel to the mine site on Wednesday.

Nasa's Dr Michael Duncan told a news conference he didn't think the long wait would be a surprise to the miners.
