SINN FÉIN PRESIDENT Gerry Adams has offered himself or any other member of his party to act as a mediator in talks with dissident republicans.

His offer, delivered on RTÉ’s Morning Ireland programme, was in response to the thousands of people who walked for peace in Omagh yesterday following the murder of Catholic PSNI constable Ronan Kerr in a car bombing.

Three men have been detained in relation to the murder and dissident republicans who are opposed to the peace process have been blamed for the attack.

Speaking to RTÉ, Adams said:

To these groups themselves, I want to offer myself or anyone in the Sinn Féin leadership or indeed anyone else who they may choose, to talk to them and to listen to them.

Adams named dissident republican groups such as the 32 County Sovereignty Movement, Éirigi, Republican Sinn Féin and the Republican Network for Unity and called on them to echo his call for an end to the violence.

Yesterday, the PSNI were given an extra five days to question a 33-year-old man arrested in Omagh on Friday.

Already a 26-year-old man and a 40-year-old man are being held and police have been given extra time to question them.

Last week, a “sophisticated” bomb was found on the main Belfast to Dublin road near Newry with the PSNI later saying the 500lb device could have caused huge devastation and loss of life.
