The bodies of 36-year-old Hatice Akçabay and her one-year-old son were found in different spots on the Evros River, in Turkey’s northwestern Edirne province, Turkish media reported.

Akçabay and her three children went missing after a boat carrying Turkish asylum seekers who fled Turkey due to an ongoing government crackdown on followers of the Gülen group capsized in the Evros River along the Turkey-Greece border on Wednesday night. Euronews identified the missing as 36-year-old Hatice Akçabay and her three sons, seven-year-old Ahmet Esat, five-year-old Mesut and one-year-old Aras. Meanwhile, the news portal said 5 others from the same boat were rescued by Greek officials.

The Yeni Hamle online news portal reported Thursday that Turkish police detained the children’s uncle Yusuf Akçabay. Akçabay “was trying to get officials to start rescue operations,” Yeni Hamle said.

Main opposition Republican People’s Party (CHP) deputy Sezgin Tanrikulu tweeted that Edirne governor has confirmed search and rescue operations have been launched to find those missing.

In the meantime, Murat Akcabay, the missing children’s father and one of those who were rescued, sought help in video recording posted online the same day.
