Five people, including three children, died after a boat carrying 15 migrants sank off the coast of western Turkey on Monday, the Turkish coast guard said.
It said five others were missing and a search was underway.
The group was made up of 14 Afghans and one was an Iraqi citizen.
The coast guard said it had plucked three people from the sea with the help of local fishing boats after the vessel with the refugees aboard went down off the coast of the western province of Izmir.
Although their numbers have decreased in recent years, migrants still try to cross into Greece from nearby Turkey in the hopes of making their way to other European countries.
