Italy’s new government barred a migrant rescue ship from docking at its ports on Friday, in its third such refusal this month, hours after a tense meeting of European leaders over migration ended. Transport Minister Danilo Toninelli said in a statement he had received a formal request from the interior ministry, headed by far-right leader Matteo Salvini, to deny Spanish charity Proactiva Open Arms entry on the grounds that it was a danger to public order.
