Northern Ireland terror threat level raised in Great Britain
The threat level from Northern Ireland-related terrorism in Great Britain has gone up from moderate to substantial.
It means an attack in England, Scotland or Wales is "a strong possibility".
Home Secretary Theresa May said the level, set by security service MI5, "reflects the continuing threat from dissident republican activity".
The level for Northern Ireland-related terrorism in Northern Ireland remains "severe", meaning an attack is "highly likely".
