At least eight tourists were killed in flash floods in south China’s Guangdong province, the government said on Sunday.

The tourists were rafting in a river in Jiangmen city when they were drowned in the sudden flood on Saturday, Xinhua news agency reported.

At least six people were saved and five were confirmed dead on Saturday. Rescuers pulled three more bodies from the river early Sunday.

The city government has launched an investigation into why the tourists were allowed to go rafting despite the weather warning.
