The Kremlin warned on Wednesday that the outlook for extending a deal beyond May 18 that allows the safe wartime export of grain and fertilizer from several Ukrainian Black Sea ports was not great as Russia's own such exports still faced obstacles.
The Ukraine grain Black Sea export deal was brokered by the United Nations and Turkey in July last year to help tackle a global food crisis that U.N. officials said had been worsened by the most deadly war in Europe since World War Two.
