At least 25 people have died in flood-hit central China's Henan province, 13 of them on the metro line in its capital, which has been flooded with water from what meteorologists have called the worst in 1,000 years.
About 100,000 people were evacuated to the capital Zhengzhou, where rail and road connections were disrupted and dams and reservoirs were raised to warning levels, while thousands of military personnel began rescue efforts in the province.
City officials said more than 500 people were escorted to safety from the flooded subway, and photos of trains and people in them immersed in water up to their chests in the dark appeared on social media.
"The water reached my chest," one of the victims wrote on social networks. "I was very scared, but the worst thing was not the water, but the decreasing supply of air in the car."
The rain has stopped bus services in a city of 12 million people, 650 kilometers (400 miles) southwest of Beijing, said a resident named Guo, who had to spend the night in his office.
“Therefore, many people took the subway and tragedy occurred,” Guo said.
At least 25 people have died in torrential rains that have hit the province since last weekend and seven people have gone missing, officials said at a press conference on Wednesday.
Media reported that among the dead were four residents of the city of Gunyi, located on the banks of the Yellow River like Zhengzhou, after the widespread collapse of houses and buildings due to rains.
More rain is forecast in Henan province over the next three days, and the People's Liberation Army has dispatched more than 5,700 soldiers and personnel to assist with search and rescue efforts.
Zhengzhou received 617.1 mm (24.3 inches) of precipitation from Saturday to Tuesday, which is almost the same as the annual average of 640.8 mm (25.2 inches).
According to meteorologists, in three days there was as much precipitation as only "once in a thousand years."
