MI5 warning on dissident threat to UK
Published 12/05/2016 | 02:30
MI5 has raised the terror threat posed to Britain by Northern Ireland-related terrorism from "moderate" to "substantial".
This means a terrorist attack is thought to be a "strong possibility".
UK Home Secretary Theresa May told the House of Commons the change "reflects the continuing threat from dissident republican activity".
She added: "As a result of this change, we are working closely with the police and other relevant authorities to ensure appropriate security measures are in place."
The stark warning from the Home Secretary comes after two men were shot dead in Belfast in the last month.
The Home Office advised members of the public to remain vigilant and report any suspicious activity.
The threat level to Northern Ireland from Northern Ireland-related terrorism has not changed from "severe".
