VALLETTA, Malta (AP) — Tens of thousands of people seeking better lives are expected to trek across deserts and board unseaworthy boats in war-torn Libya this year in a desperate effort to reach European shores by way of Italy. Some European leaders are warning of a fresh migration crisis when sea waters warm again and more people choose to put their lives in the hands of smugglers. The 28-nation EU already has a controversial deal to stem the flow of migrants from Turkey, which has agreed to try to stop the number of migrants leaving the country and to take back thousands more in exchange for billions of euros to help Syrian refugees in Turkey, visa-free travel for its citizens and fast-track EU membership talks. [...] the EU wants to adapt this outsourcing pact to the African nations migrants are leaving or jumping off from to reach Europe, despite criticism that the agreement sends asylum seekers back to countries that could be unsafe for them. The number of people arriving in the Greek islands, for instance, plunged over the last year despite political wrangling over whether Turkey's government was respecting the conditions to secure visa-free travel in Europe's Schengen area, where passport checks are not required. "The reality of Libya right now is that there is no unified government controlling all parts of the country, and no end of groups willing to upend things if there is an advantage in it for them," Carlo Binda, a Libya expert with Malta-based political and development advisers, Binda Consulting International.
