A Russian military delegation arrived in Istanbul on Wednesday to meet their Ukrainian and Turkish counterparts and U.N. officials for talks on resuming exports of Ukrainian grain from the Black Sea port of Odesa as a global food crisis worsens. 

Turkey has been working with the United Nations to broker a deal after Russia’s Feb. 24 invasion of Ukraine sent prices soaring for grains, cooking oils, fuel and fertilizer. Turkish Defence Minister Hulusi Akar announced the latest talks on Tuesday.
