SINGAPORE, June 21 (Bloomberg: Singaporean authorities found 13 new coronavirus cases locally, as the government widened mandatory testing in a large neighborhood outside the city center where a cluster has been expanding since mid-June.

More residents and housing blocks in the Redhill neighborhood will have to get tested as viral fragments were found in waste water samples collected from the area, the Health Ministry said, raising concerns of an undetected spread. The move comes as five out of the 13 cases on Monday were untraceable, government data showed.
