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.

NKHP, another large grain terminal at Novorossiysk with an export capacity of 7.1 million tonnes per year, was also damaged and had halted operations, three industry sources told Reuters. OZK, its principal owner, said in a statement that it had been damaged and that nobody had been hurt. It said it would provide further details when they became available.

Aside from grain export terminals, Novorossiysk also plays host to oil export infrastructure, including for the Caspian Pipeline Consortium (CPC), which is owned partly by U.S. oil majors Chevron and Exxon and carries Kazakh oil exports to market.

The FT reported on Wednesday that Ukraine has halted its strikes on tankers servicing the CPC, after a request from U.S. Vice President JD Vance.

There was no indication that the CPC, or tankers collecting oil from the pipeline, had been struck during the overnight attacks.
