South Korea posted its second-highest daily number of coronavirus cases on Saturday as outbreaks at a prison, nursing homes and churches continued to grow, prompting authorities to plead for a halt to all year-end gatherings.

The Korea Disease Control and Prevention Agency (KDCA) said there were 1,132 new coronavirus cases on Friday, not too far off the record of 1,241 logged a day earlier.

"The virus is spreading whenever and wherever it wants," Health Minister Kwon Deok-cheol told an intra-agency meeting, adding that people were also being infected at small gatherings with friends and acquaintances.
