As Northern Ireland counted the cost of a week's violence and bloodshed following the introduction of internment by the Northern Ireland Government, spokesmen for the Republican Movement commented on the situation from the safety of Dublin, the Eire capital. Meanwhile, troops at the border searched northbound vehicles.

One speaker was cheered as he spoke from the steps of Dublin Post office in O'Connell Street, shrine of Irish nationalism.

An official of the Irish Republican Army, identified as Mr. McSteven, answered questions on the Press conference given earlier by the militant "Provisional" wing of the IRA in Belfast.

His comments reflect the republican belief that the British army peacekeeping force in Northern Ireland is committed to the support of the Protestant majority and the suppression of the Catholic minority.
