Record rains pound South Korea killing at least four

Record torrential rainfall battered the South Korea's southern regions Wednesday, leaving at least four people dead and disrupting train services, Yonhap News Agency reported.

Parts of North Jeolla Province experienced record downpours starting early Wednesday morning. Gunsan, 178 kilometres south of Seoul, received 131.7 millimetres within a one-hour period until 2:42 a.m., marking the heaviest hourly downpour on official record nationwide.

The hourly precipitation accounts for over 10 per cent of the city's average annual rainfall of 1,246 mm.

Torrential rain also led to the cancellation of 21 flights at Gimhae International Airport in the southeastern port city of Busan and delays for 16 others.

All train services on the Janghang Line in South Chungcheong Province and the Gyeongbuk Line in North Gyeongsang Province have been suspended till 6:00 p.m.
