Rescuers in South Korea are battling to reach people trapped in a flooded tunnel, while at least 37 people have died after heavy rains caused flooding and landslides.
South Korea is at the peak of its summer monsoon season and there has been heavy rainfall for the last four days, causing a major dam to overflow.
The interior ministry reported that 37 people had been killed in the heavy downpours, mostly buried by landslides or after falling into a flooded reservoir.
On Sunday, hundreds of rescue workers were struggling to reach more than 10 cars and an unknown number of people trapped in a 430-metre (1,410ft) underground tunnel in Cheongju, North Chungcheong province, the ministry said.
Emergency workers were trying to drain the tunnel as the deep water hampered search efforts.
The tunnel was inundated on Saturday morning after flood waters swept in too quickly for the vehicles inside to escape, according to the Yonhap news agency. Five people were rescued from a bus in the tunnel on Saturday, and nine bodies have so far been pulled from the site.
The police have received missing person reports for 11 people believed to be in the tunnel, but a final official toll has not yet been provided as it was unclear how many people were in each car, Yonhap reported.
“I have no hope but I can’t leave,” a parent of one of those missing in the tunnel told Yonhap. “My heart wrenches thinking how painful it must have been for my son in the cold water.”
Images broadcast on local television showed a torrential stream of water from a nearby river that had burst its banks flooding into the tunnel, as rescue workers struggled to use boats to get to people inside.
The South Korean president, Yoon Suk Yeol, who is on an overseas trip, held an emergency meeting with his aides on the government’s response, his office said. Earlier, he ordered the prime minister, Han Duck-soo, to mobilise all available resources to minimise casualties.
Many of the casualties – 19 dead and eight missing – were from North Gyeongsang province where massive landslides engulfed houses with people inside.
Some of the people who have been reported missing were swept away when a river overflowed in the province, the interior ministry said, and more than 1,500 people have been unable to return after evacuating from their homes.
The Korea Meteorological Administration forecast more heavy rain until Wednesday and urged the public to refrain from going outside.
South Korea is regularly hit by flooding during the summer monsoon period, but the country is typically well prepared and the death toll is usually relatively low. Scientists say climate change has made weather events around the world more extreme and more frequent.
South Korea endured record-breaking rains and flooding last year, which left more than 11 people dead. They included three people who died trapped in a Seoul basement apartment of the kind that became internationally known because of the Oscar-winning Korean film Parasite.
The government said at the time that the 2022 flooding was the heaviest rainfall since Seoul weather records began 115 years ago, blaming climate change for the extreme weather.
