The deputy mayor of Odesa in Ukraine is warning of a global food crisis due to Russia's blockade of grain exports from the port city.
Oleg Bryndak spoke to NHK on Friday. He said grain prices could surge in developed nations if the situation continues, adding that people in Africa could suffer from hunger.
Odesa's port is Ukraine's largest. Bryndak said Russia is blocking access to the Black Sea, and about 80 ships are unable to depart.
Fighting is intensifying near Odesa. Ukrainian forces are trying to recapture Snake Island in the Black Sea.
