Last month eight people, including six children, were recovered after a migrant boat sank off the Greek island of Samos.
So far this year, more than 50,000 migrants have arrived in Greece by boat, making it the second most used European migrant route behind only Italy.
Migrant arrivals had been steadily declining since August 2023, but increased again since the summer, according to data, external from United Nations refugee agency, UNHCR.
About 180,000 migrants have arrived in Europe by sea this year, agency figures show, while 2,000 people were dead or missing. Around 23% of arrivals were children.
