SEOUL (Reuters) - South Korea warned of a second wave of the new coronavirus on Sunday as infections rebounded to a one-month high, just as the authorities were starting to ease some pandemic restrictions.

"It's not over until it's over," President Moon Jae-in told the nation, saying a new cluster shows the virus can spread widely at any time, and warning of a second wave late this year.
