China quake: Rescue teams use dynamite to clear roads
Chinese rescuers have used dynamite and heavy equipment to clear roads into some of the remote hill villages devastated by the earthquake that hit Sichuan province on Saturday.
Rescue teams have struggled to get lorries carrying the necessary supplies in, as many of the narrow roads are blocked by landslides.
At least 188 people are known to have died in the quake, state media says.
