Italy has suspended the Schengen free-travel arrangement with Spain in response to the migrant crisis in the Spanish enclave of Ceuta, authorities announced Friday, marking an extraordinary measure within the European Union's passport-free zone.

Italy does not have a land border with Spain but the measure will impact people travelling by plane or boat between the two countries.

Italy's interior ministry said in a statement it had also agreed with Paris to strengthen controls along the Franco-Italian land border.
