South Korea sees at least 11 deaths amid historic flooding

Seoul, South Korea saw the heaviest rain the capital has seen in 115 years as a weather system moved over the northern part of the country and prompted the city to take action.

The city has revived a $1.15 billion plan to improve drainage after the flooding exposed how even its affluent Gangnam district is vulnerable to climate change-driven extreme weather. Experts say the city's capacity to drain water is far behind what's needed to handle a deluge like what was seen this week.
