The terrorism threat in Northern Ireland has been increased from substantial to severe, meaning an attack is highly likely. In a written statement to MPs, the Northern Ireland secretary said MI5 had increased the threat from Northern Ireland-related terrorism; the public should remain vigilant but not be alarmed. The raising of the threat level comes a year after it was lowered for the first time in twelve years. Over the last 25 years, Northern Ireland has transformed into a peaceful society. The Good Friday agreement demonstrates how peaceful and democratic politics improve society. However, a small number of people remain determined to cause harm to our communities through acts of politically motivated violence. In recent months there has been an increased level of terrorist activity, targeting police and putting at risk the lives of children and other members of the public.
