The murder of Prison Officer David Black was discussed by Prime Minister David Cameron yesterday with First Minister Peter Robinson and Deputy First Minister Martin McGuinness.
Afterwards Mr Cameron branded the killing by self-styled dissident republican group, ‘the IRA’, as “cowardly”.
He said it formed part of discussions on security.
Mr Robinson said the meeting also included the progress being made on the delayed Stormont blueprint being designed to tackle sectarianism, the Cohesion, Sharing and Integration project.
A group comprising the DUP, Sinn Fein and the SDLP MLA Conall McDevitt has continued to meet on the issue.
Mr McGuinness said the topics raised had also included the reform of social security benefits.
