Zelenskyy addressed Ireland's parliament on Wednesday, where he said Russia had been blocking Ukraine's ports, stopping supplies from being brought in and out.
"In addition, Russia has blocked all our seaports, along with those vessels that have already been loaded with agricultural goods for export.
Zelenskyy also singled out the strategic port city of Mariupol, in southern Ukraine, which has been encircled by Russian troops for weeks.
"Russia has been using hunger against our people since the first days of the war. The worst is in Mariupol. This half-million city was completely blocked by Russian troops more than a month ago. They blocked access from both land and sea. Any access," he said.
"They are blocking humanitarian goods, do not allow to bring anything — food, water, medicine. When there was snow, people could melt at least the snow to get water, but now there is none."
"Why are they doing this? Because they also consider hunger as their weapon. Weapon against us, ordinary people. As a tool to dominate."
