Dutch health authorities said that 61 people who arrived in Amsterdam on two flights from South Africa on Friday tested positive for COVID-19, and they were conducting further testing early Saturday to see if any of the infections are with the recently discovered omicron coronavirus variant.

Around 600 passengers arrived at Amsterdam's Schiphol Airport on the two KLM flights on Friday and then faced hours of delays and testing due to concerns over the new virus variant.

The Dutch health ministry said early Saturday that 61 tests had come back positive.
