The new president of the Tokyo Olympic organising committee has hinted that foreign fans will not be allowed at this summer's Games amid reports in the Japanese press that a decision had already been made to exclude them.

If the situation is tough and it would make the [Japanese] consumers concerned, that is a situation we need to avoid from happening," the committee president, Seiko Hashimoto, told reporters after online talks with the International Olympic Committee president, Thomas Bach.

Authorities in Ecuador's largest city, Guayaquil, said on Wednesday they will negotiate the direct purchase of three coronavirus vaccines to speed up the immunisation process given the slow progress of the national government's rollout since January.

Guayaquil's mayor Cynthia Viteri said the goal was to vaccinate one million of over 2.6 million people in the city, which last year faced one of the worst outbreaks in the region. But the purchase requires formal authorisation from the president Lenin Moreno's government, which has yet to comment.
