Russia's decision to walk out on a deal brokered by the United Nations and Turkey to allow Ukrainian grain exports through the Black Sea has prompted fears of soaring prices and global famine. Turkey, the gatekeeper to the waterway, has a key role to play in finding a solution.
The Turkish-flagged TQ Samsun was the last ship to carry grain from a Ukrainian Black Sea port under the deal that guaranteed safe passage to cargo ships leaving the war zone, after Moscow withdrew from the agreement earlier this week.
