Irish terror threat rise worrying - Peter Robinson

Mr Robinson said that dissident groups were trying to attract the media attention.

"You have this group who clearly recognise that an incident in the Great Britain will get very significantly more media coverage than it would if it was occurring in Northern Ireland," he said.

"This is about press coverage. They know they're not going to advance their cause by it. It's just some micro groups wanting to advance their PR."

The threat from Irish-related terrorism to Britain is still lower than the overall threat from international terrorism, which remains unchanged at "severe".

The new category of threat from Ireland applies to England, Wales and Scotland but not Northern Ireland, where the level also remains "severe".
