ATHENS, Greece—At least six people died and more than a dozen were believed missing after a migrant boat capsized in the Aegean Sea late Friday, bringing to at least 20 the combined death toll from three accidents in as many days involving migrant boats in Greek waters.
The sinkings came as smugglers increasingly favor a perilous route from Turkey to Italy, which avoids Greece’s heavily patrolled eastern Aegean islands that for years were at the forefront of the country’s migration crisis.
