Black Sea grain deal in jeopardy, warns Ukraine.

Ukraine has warned that a UN-brokered initiative allowing the safe Black Sea export of Ukrainian grain is in danger of being shut down after Russia blocked inspections of participating ships in Turkish waters. The agreement was intended to help ease a global food crisis and was extended last month, but Ukraine said the number of cargo ships passing through the Bosporus carrying Ukrainian agricultural products was critically low. Russia did not respond to the comments, but the Kremlin said prospects for a renewal of the grain deal were "not so bright".
