Spain's Interior Minister Jorge Fernandez Diaz said Sunday he will make the case in Paris for a modification to the Schengen treaty allowing border controls in order to limit the movements of Islamic fighters returning to Europe from the Middle East.
"We are going to back border controls and it is possible that as a consequence it will be necessary to modify the Schengen treaty," he told the daily El Pais ahead of a ministerial meeting on the subject in Paris.
