Floods and heavy rain left four people dead and two missing in South Korea, a news agency said Saturday, citing local officials who reported landslides across the country. A 68-year-old woman and her grandchildren aged 15 and four were killed when a landslide destroyed their home in the city of Miryang, 386 kilometres (240 miles) southeast of the capital Seoul, South Korea\'s Yonhap said. The agency quoted unnamed authorities as saying a 72-year-old woman who lived near the house had been reported missing after being swept away by floodwaters. A 73-year-old woman was found apparently drowned in flash floods in the central county of Uiryeong, and emergency crews are trying to find another elderly woman in the same region, the report said. Local government officials and firefighters said around 3,000 hectares (7,400 acres) of farmland was flooded in the southwestern county of Hadong after 20 centimetres (eight inches) of rain fell in some areas.
