In Odesa, we spoke with David Beasley, the executive director of the U.N.'s World Food Programme.
David Beasley: You gotta assume that millions are at stake right now. We're reaching about 2 million already. We hope to scale up to 4 million in the weeks ahead and 6 million beyond that. It's gonna be dependent upon two things: money and access.
But access has been cut off to the war's victims in the heavily besieged cities of Eastern Ukraine.
David Beasley: We can't reach them. We're blocked. We can't get into the besieged cities like Mariupol, Mykolaiv, and Kherson, and I could go on and on. They have to be starving.
Scott Pelley: Why would the Russians not allow food to be delivered to starving people?
David Beasley: It's beyond imagination. Why would you deny innocent victims of war food, non-combatants? It's just wrong, evil.
