At least 20 people died and several others have been evacuated from their homes as flood-ravaged different regions of South Korea, media reports said.

Officials told Yonhap News Agency that 10 people remained missing and nine others were injured.

Most fatalities were reported from the southeastern province of North Gyeongsang, where 16 people died largely due to landslides and housing collapses.

Some 6,400 residents in the central county of Goesan were evacuated, as the Goesan Dam began to overflow at around 6:30 a.m. Many low-lying villages near the dam were submerged, and roads and bridges connecting the villages were cut off, trapping some residents in their homes, the news agency reported.

A total of 1,567 people from 1,002 households in 13 cities and counties were forced to take temporary shelters as heavy rainfall continued to disrupt normal life in the country.

A train derailed in Cheongju at 10:58 p.m. Friday as significant rainfall triggered a mudslide. An engine driver sustained light injuries and was taken to a hospital. No other casualties were reported, reports Yonhap.

President Yoon Suk Yeol ordered the government to "respond to the disaster to the fullest by using all resources available."
