There was a solidarity picket of the Irish Embassy in Madrid, organised by the Federación Anarquista Ibérica, the Iberian section of the International of Anarchist Federations (http://www.iaf-ifa.org/) They have also made up posters about Rossport, and carried articles in their monthly magazine, Tierra y Libertad.

I think the banner reads ‘Shell Destroys the State Complies’
