A landslide triggered by torrential rain crashed into South Korea capital Seoul, killing 32 people and leaving one child missing, emergency services said.

A report says, 10 of the 13 people killed in the landslide in Churcheon, were students who had been doing volunteer work, said Byun In-soo of the town's fire station.

"We were asleep and suddenly I heard a big sound, and then the ceiling fell down," Lee Beon-seok, a student, told a television station.

Seoul recieved about 400 mm (16 inches) of rain in the past 24 hours, causing flash floods, landslides and bridge closures. A blackout hit the south of the city, suspending train services, and inundating subway stations.
