Located since November 2019 at the "substantial" level, the level of alert to the terrorist threat was raised to "serious" Tuesday in the United Kingdom by the British security services.
This is the fourth step out of five.
It is expected when a terrorist attack is considered "very likely," according to MI5, the internal intelligence service, which announced the change on its website.
"It is a precautionary measure which is not based on a particular threat," said Interior Minister Priti Patel, the day after the Vienna attack and after several attacks in France.
Three attacks in one year
The UK has been the scene of several attacks deemed terrorist in recent months.
In November 2019, a jihadist on parole killed two people in the heart of the capital, before being shot dead by police on London Bridge.
On February 2, three people were stabbed in a shopping street in an attack "of an Islamist nature", according to the police.
The assailant was also killed by the police.
On June 20, a knife attack left three people dead in a park in Reading about sixty kilometers west of London.
The suspect was known to the intelligence services.
Priti Patel then indicated that the security services had foiled 25 plans for attacks over the past three years, including eight fomented by the extreme right.
She had worried about the growing threat posed by “isolated actors”.
