Political representatives of rival loyalist groups have confirmed that there are no plans for further meetings between them to resolve the ongoing feud which has left three people dead.
The leader of the Progressive Unionist Party, which represents the UVF, Mr David Ervine, said he intended to "stay in touch" with Mr Davy Adams from the Ulster Democratic Party (the political wing of the UDA and UFF). However, he added that the two sides had not arranged a further meeting when they held crisis talks on Friday.
Both Mr Ervine and the UDP leader, Mr Gary McMichael, said they had agreed not to comment on Friday's talks. However, senior sources within loyalism believe that there is not "the will on the ground" to end the feud.
Mr McMichael said he was "greatly encouraged" that there had been no violence on Belfast's Shankill Road on Saturday night.
The same night, however, the RUC discovered an arms and ammunition cache, including mortar tubes, a handgun, ammunition and a number of suspect devices, during a search of an abandoned house in Snugville Street, just off Shankill Road.
The UVF has been blamed for an arson attack which destroyed a well-known loyalist drinking club on the lower Shankill Road on Friday night. The Pony Club, on Malvern Street, was believed to be frequented mainly by UDA/UFF members. Mr Ervine yesterday rejected the claim.
The British army has confirmed that it is bringing back the Royal Marines' 40 Commando to Northern Ireland to relieve the Royal Green Jackets' 1st Battalion in its patrol duties on the Shankill Road.
Meanwhile, the wife of the leading loyalist, Mr Johnny Adair, has handed in two letters to Downing Street calling for Mr Adair's release from prison.
Mr Adair had been freed last year, but was rearrested in August. A leading UDA member, he was believed to have played a major role in the loyalist feud.
Ms Gina Adair was accompanied by around 20 supporters. She said the letters called on Mr Blair to state what crimes Mr Adair was being accused of or else to free him from prison.
According to reports in several Sunday newspapers, the RUC has started an investigation into Mr Adair's financial dealings under the Proceeds of Crime Order. An RUC spokesman yesterday said he would not confirm at this stage whether such an "assets tracing probe" was taking place.
Meanwhile, shopkeepers across Northern Ireland have been put on alert after two incendiary devices were discovered in stores in Belfast and Armagh. Army bomb disposal experts were called to deal with a device at Milletts' sports clothing store at Belfast's Cornmarket, while a fire-bomb was discovered in a soft furnishing shop in English Street, Armagh on Saturday afternoon.
An RUC spokesman said it had not yet established who had planted the devices.
A Sinn Fein councillor, Mr Sean Hayes, said he believed loyalists were responsible for two attacks on houses in Rutland Street, off the nationalist Lower Ormeau Road, on Friday night.
A petrol bomb was thrown at one house, while the window of another was broken. The RUC has not yet confirmed whether the attack was sectarian.
