European leaders are meeting in Valletta, Malta, for a one-day informal summit. The EU wants to step up its efforts to tackle illegal migration -- and it believes a deal with Libya is crucial. The goal is to close the route from Libya to Italy. EU Council President Donald Tusk says an agreement with Libya is the only way to curb migration to Europe. The EU currently maintains naval operations in international waters, with a mandate to intercept smugglers' boats. This year alone, over 4000 migrants and refugees have made the journey by sea to Italy.
