“The terrorism threat level in Northern Ireland has been raised from ‘substantial’ to ‘severe’ just days before a potential visit to the country by US President Joe Biden, but the White House has said the change won’t alter his plans. The decision to raise the threat level to ‘severe,’ meaning an attack is highly likely, was made by the UK’s MI5 security service and announced by UK Secretary of State for Northern Ireland Chris Heaton-Harris on Tuesday. Heaton-Harris said the move was made after an increase in ‘activity relating to Northern Ireland-related terrorism’ including the attempted murder of a high-profile police officer last month. While the public should remain vigilant, they should not be alarmed, he said.”
