The death toll from landslides in China, which has been experiencing extreme weather in recent weeks, has doubled overnight.

Chinese officials say at least 702 people were killed after a mass of mud and rock rushed through a town in remote Gansu province at the weekend.

More than 1,000 people are still missing, as thousands of soldiers and volunteers continue to dig round-the-clock to try to find survivors.

One 52-year old man was pulled out alive on Tuesday, but rescue efforts are now being threatened with forecasts of more rain in the coming days.
