Two days of heavy rain in South Korea have killed at least seven people and left two others missing in landslides and floods, according to the government. Additionally, eight people were trapped following landslides in central areas earlier on Saturday.
Three people died on Saturday in their houses in the eastern county of Yeongju and the central county of Cheongyang, the Ministry of the Interior and Safety said in a report.
It said two other people were also found dead elsewhere in landslide-related accidents, and another two people died in a building collapse in the central city of Nonsan, South Chungcheong province, on Friday.
Two people are feared to have been killed when a landslide destroyed a home in Bonghwa, North Gyeongsang province.
South Korean media reported on Saturday that three more people were officially considered missing. The number of victims could rise further, the authorities said.
