LONDON (Sputnik) — Earlier in the day, Metropolitan Police chief Bernard Hogan-Howe told to the Daily Mail newspaper that the terrorist threat remained at "severe" level and an attack was highly likely to happen.
"There's four or five cases where there is a sense of a plot, where they are planning and plotting and intending to commit an act of terrorism rather than just being extremists," the official told the Sunday Times newspaper.
Europe has been pushed to urgently and extensively boost its safety and security measures over the past two weeks amid a wave of deadly attacks that has occurred in Europe, including a truck running over a crowd in France's Nice and a suicide bombing near an open-air music festival in Ansbach, a city in the German state of Bavaria.
