Authorities in Turkey are investigating eight bodies that washed up in the Mediterranean province of Antalya, including two found Monday on a beach in the vacation resort of Serik.

The Antalya governor’s office said one body is assumed to be a Turkish citizen who was reported missing.

Authorities believe the seven other bodies discovered over the past week may be migrants from a boat that went missing off the coast near the Syria-Lebanon border last month on its way to Cyprus.

An estimated 90 people were on board the boat that disappeared on Dec. 11, the governor’s office said, citing information provided by the Lebanese embassy in Turkey.

An evaluation of currents, winds, and waves indicates that the victims may have been dragged toward the Antalya coastline, the office said in a statement.
