Torrential rain has killed 15 people in the Chinese city of Chongqing, as President Xi Jinping called for greater efforts to protect the public from extreme weather.

Heavy downpours have unleashed devastating floods and deadly mudslides in recent weeks, while hail storms and unusually high temperatures, which many people suspect is the result of global warming, have brought misery to many parts of the country.

In the sprawling city of Chongqing, floods have forced thousands from their homes, bridges have been destroyed, and homes and cars washed away.

As well as the 15 people killed over recent days, four were missing as of early Wednesday, the state-run Xinhua news agency reported, citing authorities.

The latest round of heavy rain has disrupted the lives of more than 130,000 people and damaged more than 7,500 hectares of crops, the agency reported.

In the Wanzhou district, north-east of Chongqing, floods have caused 227.8 million yuan ($47.2 million) worth of economic losses, state broadcaster CCTV said.

Videos on social media showed raging rivers in towns and cities, and people being evacuated through waist-deep water.

One clip showed rescuers breaking through a window security mesh to reach people trapped in an apartment.

Mr Xi demanded that authorities at all levels give top priority to ensuring the safety of people and property, and he called on the State Flood Control and Drought Relief Headquarters, and the ministries of emergency management and water resources, to improve their coordination and warnings, Xinhua reported.

The finance and emergency management ministries announced 320 million yuan in emergency funds to aid disaster relief, including for Chongqing.

The Ministry of Water Resources launched flood emergency responses for the Inner Mongolia region, and Liaoning, Jilin and Heilongjiang provinces, CCTV reported.

Heavy rain is expected in those areas on Wednesday, state media reported.
