WASHINGTON: The U.S. State Department on Monday urged against travel to Japan and Sri Lanka due to new waves of COVID-19 infections, saying those two nations will now fall under the department's "Level 4: Do Not Travel" advisory.

The State Department said it saw a lower risk in visiting the Caribbean nation of Antigua and Barbuda?, lowering that nation to a "Level 3 - Reconsider Travel" designation.

The U.S. warnings come just two months before the Tokyo Olympics are set to get under way, something a top Olympic officials last week said would happen even under a state of emergency after being postponed last year.
