The UK threat level was raised from substantial to severe on Monday, meaning further terrorist attacks are “highly likely” after a taxi exploded on Monday outside a Liverpool hospital, killing the male passenger. He is believed to have been a suicide bomber who was aiming to blow up a church nearby. Home secretary Priti Patel said the terror threat level had been raised after two such attacks in the space of a month. The murder of MP David Amess on Oct. 15 by an explosive device in his car is now rated as the first.
PM Boris Johnson praised the taxi driver, saying he appeared to have behaved “with incredible presence of mind and bravery.” Four people have been arrested in connection with the incident.
