A woman died after a migrant boat sank off the coast of Lesvos Island in Greece on Sunday, Greek authorities said.
Seventeen people were rescued, while a search and rescue operation involving the Hellenic Coast Guard (HCG) and the European Border and Coast Guard Agency (Frontex) was ongoing, according to the HCG.
The nationalities of the victim and the rescued migrants have not yet been determined.
Since 2015, Greece has been a key entry point for irregular migrants and refugees seeking to reach the European Union, with more than one million arrivals recorded. Hundreds have died at sea while attempting the dangerous crossing.
