South Korea Suffers Worst Rainfall in Eight Decades

SEOUL—South Korea’s heaviest rainfall since World War II submerged cars on the streets, flooded subway stations and left at least eight people dead.

The downpours also hit neighboring North Korea, which added to the chaos by discharging floodwaters near the two countries’ border without giving advance notice as required by an inter-Korean accord. Water levels near one border-area bridge rose to nearly 17 feet Monday afternoon, or six times higher than normal, South Korean officials said.
