The UK’s terror threat level has been raised from substantial to severe.
It comes after an explosion outside Liverpool Women’s Hospital on Remembrance Sunday was declared a terror incident by police.
Four men have now been arrested in connection with the incident, in which a taxi exploded at a drop-off zone near the entrance to the hospital.
The driver of the taxi, named locally as David Perry, was able to escape the blast, whilst the passenger was killed by a homemade bomb.
Perry has now been discharged from hospital after receiving treatment, with Prime Minister Boris Johnson praising him for behaving with “incredible presence of mind and bravery”.
On Monday, the UK’s home secretary Priti Patel confirmed the change in the threat level following the blast.
She said: “The Joint Terrorism Analysis Centre, Jtac, are now increasing the United Kingdom’s threat level from substantial to severe.
“And there’s a reason for that, and that reason is because what we saw yesterday is the second incident in a month.”
An investigation is being carried out by police, with two addresses in Liverpool being searched.
