Rescue workers recovered nine bodies from cars stuck inside a flooded tunnel in the South Korean city of Cheongju, as days of heavy rain submerged buildings and trapped many people inside.

Earlier, officials had said that nine people were reported missing.
It is unknown how many passengers and drivers are trapped under the 685-metre-long submerged tunnel in the city of Osong, however, it is said to contain 15 vehicles.
Some bodies were taken out in a bus while nine people were rescued on Saturday.
