Two of Russia's biggest grain terminals at the southern port of Novorossiysk have suspended operations as a result of overnight Ukrainian drone strikes.

That is according to Reuters, citing four industry sources, Ukrinform reports.

Russia is the world's largest wheat exporter and most of those exports are shipped via its Black Sea ports like Novorossiysk.

Russia's main grain lobby group warned last month that Ukrainian ⁠drone attacks could shut down grain exports via the Black Sea in the near future, pushing up prices and causing hunger in Africa and the Middle East.

One industry source, who declined to be named due to the matter's sensitivity, said the Novorossiysk grain terminal – which has an export capacity of 8.5 million tonnes per year – had suspended operations and an assessment of the damage was underway. A spokesperson for Demetra Holding, which owns the terminal, only said that the terminal had sustained unspecified damage and declined to comment further.
