Mudslides and flash floods caused by days of heavy rain have left seven people dead and six missing in South Korea, officials said Saturday. Four people were killed in Chunyang village in the southeastern county of Bongwha, where hundreds of others were forced to evacuate after floodwaters and mudslides hit their homes, the National Emergency Management Agency said. Two people were killed when hillocks caved in on their house on Friday, while two drowned in a flashflood as they were climbing down a hill, it said.
