A huge dam in Ukraine was breached on Tuesday, creating a natural disaster.
Ukraine said Russia blew up the damn to try and hamper Ukraine's counteroffensive.
An expert said the flood will make it harder to Ukraine to reach occupied territory over the Dnipro river.
Podolyak's comment suggests he thinks Russia would struggle to keep Ukraine back without taking such action.
Russia and Ukraine both warned earlier in the war that the other side may target the dam.
