Floods and landslides caused by heavy rains in the Republic of Korea (ROK) have forced more than 1,000 people to evacuate their residences, besides leaving at least 13 dead and another 13 missing, the Central Disaster and Safety Countermeasure Headquarters said on Tuesday.

Deaths were reported from landslides and vehicles swept away by water that disaster officials said inundated more than 5,751 hectares of farmland and flooded parts of key highways and bridges in the capital, Seoul.

A total of 1,025 people from 629 households fled their homes. More than half of them were in North Chungcheong Province, followed by 391 in Gyeonggi, 70 in Gangwon and nine in Seoul.

At an emergency meeting held at Cheong Wa Dae, ROK President Moon Jae-in urged relevant ministries to take preventive measures to the "extent that could be seen as excessive."

Moon also reminded officials to pay attention to possible landslides and put their best efforts toward "prevention of additional casualties by restricting access to dangerous areas and evacuating areas preemptively."

"Due to a lot of rain, damage has been reported in the central region, prompting streams and reservoirs to overflow, toppling embankments and submerging underpasses. Outdoor activities should be refrained from as more damage is expected from rain," the weather agency said.

Weather forecasts also added that the downpour is likely to continue for the next few days in parts of Seoul as well as Gyeonggi and North Chungcheong provinces.

Work crews had returned to operation by Tuesday most of the flooded roads and bridges along the Han River in central Seoul that had backed up traffic and damaged infrastructure, the Yonhap News Agency said.

In neighboring Democratic People's Republic of Korea (DPRK), state media warned of possible flooding, saying that some areas were also experiencing heavy rainfall.
