Northern Ireland terror threat level raised in Britain
The threat level from Northern Ireland-related terrorism in Britain has been raised 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 at severe, meaning an attack is "highly likely".
At Easter the New IRA, the group responsible for the murder of prison officer Adrian Ismay in March, warned that its members were "determined to take the war to the age-old enemy of our nation".
The threat level for Northern Ireland-related terrorism was raised from moderate to substantial in 2010, then reduced back to moderate in 2012.
