Russia is ready to provide a humanitarian corridor for vessels carrying food to leave Ukraine, Moscow’s deputy foreign minister Andrei Rudenko said on Wednesday, as concerns grow over a global food shortage due to the war.

       Russia’s invasion has sparked a global food crisis that the UN has warned could starve millions and lead to civil unrest in hunger-prone countries.

       Russia has blockaded Ukrainian ports, stopping exports from one of the world’s biggest grain producers and sending food prices skyrocketing around the world.
