Britain's intelligence service MI5 reviewed the terror threat level of Northern Ireland and raised it to 'severe' from 'substantial'. Authorities advised citizens not to be alarmed, but vigilant.
The UK's MI5 intelligence service revised the terrorism threat level amid an increase in activity by dissident Irish republican militants.
Severe is the second-highest rung on a five-point scale and means an attack is considered highly likely. The threat had stood one notch lower at 'substantial' for the past year.
Paramilitary groups in Northern Ireland laid down their arms after the 1998 Good Friday peace accord largely ended three decades of violent conflict between Irish republican and British loyalist groups and UK security forces that killed more than 3,600 people. But small Irish Republican Army splinter groups have continued to launch sporadic attacks on security forces.
Northern Ireland Secretary Chris Heaton-Harris said that in recent months, we have seen an increase in levels of activity relating to Northern Ireland-related terrorism, which has targeted police officers serving their communities and also put at risk the lives of children and other members of the public. He urged people to remain vigilant but not be alarmed.
Chris Heaton-Harris said, “In recent months, we have seen an increase in levels of activity relating to Northern Ireland-related terrorism, which has targeted police officers serving their communities and also put at risk the lives of children and other members of the public. These attacks have no support, as demonstrated by the reaction to the abhorrent attempted murder of DCI Caldwell.”
Last month, senior police officer John Caldwell was shot by two masked men as he coached a children's soccer team in the town of Omagh, nearly 100 kilometres west of Belfast. Police say he suffered life-changing injuries. An IRA splinter group known as the New IRA claimed responsibility.
The change to the threat level comes ahead of events commemorating the 25th anniversary of the Good Friday agreement.
US President Joe Biden is expected to visit Northern Ireland to mark the anniversary. Major players in the peace process, including former US President Bill Clinton and ex-British Prime Minister Tony Blair, are also due in Belfast for commemorative events.
The threat level for the rest of the UK remains at substantial, meaning an attack is considered likely.
