Diehard republicans have vowed to kill Sinn Fein councillors over their support for district policing partnerships.
The Irish Republican Liberation Army (IRLA) has ordered the party's DPP members to quit their positions before Christmas or face "military action".
A spokesman for the terror group - which has former IRA and INLA men within its ranks - also vowed to step up its campaign of violence in 2008.
Our exclusive pictures of the newly-formed dissident republican gang were taken at a secret location in Belfast.
They include a masked terrorist brandishing an AK-47 assault rifle.
Said the IRLA leader: "All Sinn Fein members in the North have 14 days to resign from the DPPs or military action will be taken against them.
"This is a direct response to the Sinn Fein leadership inviting police into republican west Belfast.
"The present strategy of the Gerry Adams and Martin McGuinness is not the way forward. We believe we are the way forward.
"We are going to step up our campaign through the use of armed struggle and we intend to mount attacks against the Crown forces in the six counties. We were established to end British rule in Ireland and defend the six counties against British imperialism."
The sinister threats were issued after Chief Constable Sir Hugh Orde told the Policing Board last week that renegade republican weaponry had become " more sophisticated".
The IRLA were responsible for issuing death threats against top Sinn Fein members, including veteran republican Martin Meehan's widow Briege, last month.
North Belfast Sinn Fein MLA Gerry Kelly said republicans were taking the threats seriously.
He said: "There is anger within the community over the fact that people like Briege Meehan are being targeted."
The group also claimed responsibility for the murder bid on a police officer in Dungannon, but this was later dismissed by the Real IRA.
Security sources believe the new terror group's stronghold is in north Belfast.
