Russian authorities say they turned back a Turkish-controlled bulker after finding traces of explosives.

The Federal Security Service (FSB) said the evidence of explosives was found on the 1,610-dwt general cargo ship BMO River (built 1986), according to Reuters. It was the second such discovery claimed by Russian authorities in a week.

The Palau-flag ship is controlled by Marine Inspektor of Turkey, according to Clarksons.
