 The first vessel that used Ukraine's Black Sea corridor is crossing through Turkey's Bosphorus Strait, Reuters footage showed on August 18. The Hong Kong flagged Joseph Schultz container ship that left the Russian-blocked Ukrainian Black Sea port of Odessa earlier this week had been in the port since February 23, 2022, the day before the start of Russia's full-scale invasion of Ukraine. Ukraine last week announced a humanitarian corridor in the Black Sea to release cargo ships that have been trapped in its ports after the termination of the main grain export deal last month. Moscow has not indicated whether it would respect the shipping corridor and shipping and insurance sources have expressed concerns about safety. Local broadcasters have said the ship will anchor at Ambarli port in the south of Istanbul.
