The Turkish authorities confirmed a total of 42 deaths in the shipwreck in Lake Van in southeastern Turkey three weeks ago on Friday after two new bodies were discovered, one of which was a child.
The identity of the victims has not been disclosed and five people have been arrested in connection with the incident, the Turkish news agency Anatolia reports.
According to Turkish Interior Minister Suleiman Soylu, the ship was destroyed on July 27 with 60 migrants. The remains of the ship were found at a depth of 106 meters near the border with Iran.
Van Lake is a regular border crossing for refugees trying to get to Europe from the Middle East.
In December, it was the scene of another shipwreck that killed at least seven people. The migrants were then identified as people from Pakistan, Bangladesh and Afghanistan.
