Turkey closes the Bosphorus Strait
"Due to bad weather conditions, the Bosphorus strait near Istanbul is temporarily closed to the passage of ships in both directions," according to a statement carried by RIA.
The Dardanelles Strait was also closed to traffic earlier.
A yellow weather alert is in effect in the Istanbul area due to hurricane-force winds of up to 80 kilometers per hour.
In the past 10 days, at least five cargo ships ran aground in the Black Sea off the coast of Turkey due to stormy weather.
