IDOMENI, Greece — With Turkey in crisis and Europe’s borders closed, smugglers in northern Greece are expecting a profitable summer.
Greek police say traffickers are using increasingly sophisticated methods — motorcycle spotters, maps of border surveillance ‘‘blind spots,’’ and even police informants — to move out migrants who have been stuck in this Greek border town for months.
Higher smuggling fees and steadily worsening odds of success have done little to dent the determination of migrants.
Police said smugglers brought some 600 migrants into Greece from Turkey over several months and helped them reach other countries, using a fleet of taxis, scout vehicles, prepaid ‘‘burner’’ cellphones, and a system of code words that included: ‘‘dogs’’ for police, and ‘‘garbage trucks’’ for police cars.
