On 3 November 2020, authorities in the U.K. raised the country’s terrorism threat level to “severe,” which indicates that an attack is highly likely. The “severe” level is the second-highest alert on a five-tier scale. The terrorism threat level in the U.K. had remained at “substantial” after being downgraded from “severe” in November 2019. While the country’s home secretary stated that the increase in the threat level is a precautionary measure and not in response to a specific threat, the move comes a day after a terrorist attack occurred in central Vienna, Austria’s capital.
