RUC detectives investigating the bomb at the Killyhevlin Hotel in Enniskillen nine days ago believe it was not the work of the renegade faction linked to the first attempted bomb attack of the IRA ceasefire.
In December 1994, just four months after the IRA declared its ceasefire, British army bomb experts defused a 2 lb Semtex device which had been planted outside a furniture shop in Enniskillen.
At the time it was believed members of Republican Sinn Fein's paramilitary wing had planted the bomb.
Following last weekend's 1,200 lb bomb blast at the hotel, blame has been attributed to Republican Sinn Fein. A military organisation linked to RSF, "The Continuity Irish Republican Army" is also suspected of being behind the 1,300 lb of explosives discovered at Carrickmacross in Co Monaghan last November.
An RUC spokeswoman has confirmed that the two Enniskillen incidents, neither of which has been admitted, are not being linked.
