China earthquake: Troops join rescue effort

A rescue operation is underway in China after a strong earthquake struck the remote Yunnan province in the south-west of the country.

The country's president has called for "all-out efforts" to find survivors, as he dispatched thousands of troops to the disaster region.

At least 398 people died, and more than 1,800 were injured, when the magnitude 6.1 earthquake struck on Sunday.
