Torrential rain and landslides in southern China have killed 132 people, with more heavy rain forecast. A further 86 people are missing and 800,000 residents have been evacuated. There have also been power cuts, collapsed reservoirs and widespread damage to roads. Millions are without drinking water supplies. Dozens of rivers have passed safety levels, including the Pearl River in Guangdong province. China's rainy season, which began in May, follows the worst drought in a century in the south-west.
