Since reaching a deal with the EU in November, Turkey has stepped up its counter-smuggling efforts, increasing sea patrols, detaining thousands before they make the sea crossings, cracking down on trafficking groups and raiding workshops that produce bogus life jackets or dinghies. In return for trying to stem the flux, Turkey is to receive a $3.3 billion fund to help it deal with the refugee crisis, a much-awaited easing of EU visa restrictions for Turkish citizens and sped-up EU membership talks. The government — under pressure to get results before a key meeting March 7 with the EU — is upbeat, insisting the measures already have made a “visible difference.” In response to the crisis, NATO has ordered three warships to sail to the Aegean Sea to help Greece, Turkey and the EU border agency Frontex conduct sea patrols.
