Twelve people have died after record-breaking rainfall flooded underground railway tunnels in China, leaving passengers trapped in rising waters.
Video shared on social media shows evening commuters just managing to keep their heads above water. Water is seen rushing onto platforms.
More than 500 people were eventually rescued from the tunnels in Henan province, officials said.
Days of rain have caused widespread damage and led to 200,000 evacuations.
Above ground, roads have been turned into rivers, with cars and debris swept along in fast moving currents. A number of pedestrians have had to be rescued.
More than a dozen cities in Henan province are affected, with President Xi Jinping acknowledging on Wednesday that there had been "significant loss of life and damage to property".
Several dams and reservoirs have breached warning levels, and soldiers have been mobilised to divert rivers which have burst their banks. Flights and trains in many parts of Henan have also been suspended.
In the provincial capital Zhengzhou, the equivalent of a year's average rainfall has fallen in just three days.
On Tuesday, some of the city's flood defences were overwhelmed and water began flowing down into the railway tunnels.
Survivors have described how water leaked through the doors, rising slowly from "our ankles to our knees to our necks". "All of us who could, stood on the subway seats," one woman wrote on Chinese social network site Weibo.
