Just three days before the Summer Olympics opening ceremony, there is still a chance the Games could be canceled amid a recent spread of COVID-19 among some of the athletes.

Toshiro Muto, head of the Tokyo Olympics organizing committee, told reporters during a Tuesday press conference a late cancellation hasn't been ruled out.

"We can't predict what will happen with the number of coronavirus cases. So we will continue discussions if there is a spike in cases," said Muto. "We have agreed that based on the coronavirus situation, we will convene five-party talks again. At this point, the coronavirus cases may rise or fall, so we will think about what we should do when the situation arises."
