South Korea is grappling with severe flooding and landslides as torrential rains have lashed the country for three consecutive days. At least four fatalities have been reported, with additional individuals missing and thousands evacuated to safety. The heavy downpours are being described as the most intense in 120 years, triggering mass evacuations and road closures. Communities near US military bases are particularly affected, with stranded vehicles and disrupted transport services. The situation remains critical as authorities brace for more extreme rainfall this weekend.
