The South Korean Disease Control Center has announced a fifth death from COVID-19 coronavirus.

South Korea reported 123 new confirmed coronavirus cases, taking the national tally to 556.

More than half the additional cases were found to be linked to a church in the southeastern city of Daegu after a 61-year-old woman known as "Patient 31" who attended services there tested positive for the virus last week.

South Korean President Moon Jae-In has declared the highest alert level in the country due to the spread of the virus.
