China is continuing a massive rescue operation in Sichuan province, deploying thousands of workers, after a powerful earthquake on Saturday.

Rescue workers are using dynamite and heavy equipment to get through roads blocked by landslides to reach remote areas, reports say.

At least 188 people are known to have died in the quake, says state media.
