Russia and Ukraine met UN and Turkish officials on Wednesday in a bid to break a months-long impasse over grain exports that has seen food prices soar and millions face hunger, France 24 reports.
The high-stakes meeting in Istanbul came with Russia's invasion of Ukraine showing no signs of abating and the sides locked in a furious long-range shooting battle that is destroying towns and leaving people with nothing.
Ukrainian officials said at least five people were killed in Russian shelling on the region surrounding the Black Sea port city of Mykolaiv.
"You can't run away from war and you never know where it will find you," 60-year-old agronomist Lyubov Mozhayeva said, while picking up a humanitarian food package in the partially destroyed frontline city of Bakhmut.
The first face-to-face talks between Russian and Ukrainian delegations since another meeting in Istanbul on March 29 comes with the threat of food shortages spreading across the poorest parts of the world.
Ukraine is a vital exporter of wheat and grains such as barley and maize. It has also supplied nearly half of all the sunflower oil traded on global markets.
But shipments across the Black Sea have been blocked by Russian warships and mines Kyiv has laid to avert a feared amphibious assault.
