Outbreaks in S Korean schools drive Covid surge

South Korean authorities moved to rein in coronavirus outbreaks centred on Christian schools as the country reported a jump in infections, dampening hopes of a speedy exit from a third wave of the pandemic. At least 323 Covid-19 cases had been traced to churches and mission schools run by a Christian organisation in two cities. More than 100 cases were confirmed overnight among people linked to churches and its mission schools in Gwangju, about 270kms south of Seoul, officials said.
