Turkish fishermen in Black Sea closely watch navy boats

Turkish fisherman Şahin Afsüt fears the worst: Hitting a mine and "disappearing underwater in the blink of an eye."

Like many fishermen in Rumelifeneri, a village set on the rocks of the Bosphorus in northern Istanbul, Afsüt and his team remain in port since the discovery of a drifting mine last month in the Black Sea.

Fears grew after a second mine was found on March 28, which could have come from Ukraine, where Russia launched an invasion in February.

Kiev dismissed Moscow's version of events, accusing the Russian navy of letting the mines wander to discredit Ukraine.
