Typhoon Muifa passing over South Korea along its west coast left at least four dead and two others missing, the country's emergency management agency said Monday.

Muifa, the season's ninth typhoon, brought strong winds and heavy rains to multiple regions, including the southern resort island Jeju and areas of west coast on Sunday and Monday.

According to Seoul's National Emergency Management Agency, three people were killed in South Jeolla Province, including a 75- year-old man who were found dead after going missing while trying to moor a 1-ton ship in stormy seas, and one more was reported dead in the southern port city of Busan.

Two others, one in Busan and another in North Chungcheong Province, remained missing in the aftermath of torrential rains and strong winds that accompanied the typhoon, the agency added.

The typhoon also caused power failure for some 360,000 households in six areas including Jeju and South Jeolla Province. There were also some reports about seawall and roads damage in South Jeolla, one of the worst-hit regions from the typhoon.

Hundreds of domestic and international flights, mostly bound for China, were suspended due to the typhoon. But most domestic airline operations were back on track late Monday as Muifa continues to head north in the Yellow Sea.
