A prominent dissident republican is calling on Sinn Féin to state if her life is in danger from the Provisional IRA.
Ms Marion Price said the Police Service of Northern Ireland had twice visited her west Belfast home and advised her of a threat from mainstream republicans. Security sources confirmed police contacted her.
She was advised to improve her personal security. A former IRA hunger striker, Ms Price is now a spokeswoman for the 32 County Sovereignty Movement which security sources say is the political wing of the "Real IRA", a claim the group denies.
There has been speculation recently about a feud between dissident republicans and the Provisional IRA. Ms Price called on Sinn Féin to state if her life was under threat. "I am taking the situation seriously. Sinn Féin has the ear of the Provisionals and I want them to confirm or deny the threat. I know Gerry Adams and I'd like a personal response from him. If the threat is genuine, I'd like to ask why it is there.
"If it isn't genuine, then someone is trying to muddy the waters and provoke a republican feud."
Ms Price, her sister Dolours, and Sinn Féin's Mr Gerry Kelly, were jailed for life for the 1973 Old Bailey bombing. They later embarked on a hunger strike in English jails. Ms Price is now a critic of the Sinn Féin leadership and claims the peace process is a sell-out of traditional republicanism.
Speculation about a feud between the Provisional IRA and dissidents began earlier this month when Mr Adams was told his life was in danger from the "Real IRA".
