Referring to deputy first minister Mr McGuinness’s part in the power-sharing deal, the group added: “The Irish people have been sold a phoney peace, rubber-stamped by a token legislature in Stormont."
The dissidents said an “armed struggle” for Irish freedom could only be avoided by the withdrawal of British forces in Northern Ireland.
They called for an “internationally observed timescale that details the dismantling of British political interference in our country.”
Among those believed to have joined the merged division were those behind the murder of Catholic policeman Ronan Kerr in April last year as well as those who planted a bomb in the car of another Catholic officer, Peadar Heffron.
The statement will be monitored with interest by the security and intelligence services but is unlikely to change any threat assessment at this stage.
However, it is not the first time dissident groups have claimed to have joined forces only to fall apart again.
Despite claims they want to reclaim the banner of the Provisional IRA, there is nothing like the groundswell support in the region that there was in previous decades.
The Home Office refused to comment.
