LONDON (Reuters) - A deal allowing Ukraine to export grain via the Black Sea will expire at the end of Monday after Russia said it will suspend its participation.

The deal, brokered by the United Nations and Turkey last July, aimed to alleviate a global food crisis by allowing Ukrainian grain blocked by the Russia-Ukraine conflict to be exported safely.
