"torture" by starvation 

Ukrainian President Volodymyr Zelensky said Friday that Mariupol is one of the most complicated points of this war, accusing Russians of blockades and torture with starvation, during a virtual event held by policy institute Chatham House to discuss the war. 

When asked about the situation in Mariupol, Zelensky said all the international organizations — including Ukrainian ones — are prohibited from entering the area to provide water, food and other supplies to civilians.

He added that the Russian military's treatment in Mariupol is "inhuman" and a "beastly attitude." Zelensky also emphasized the importance of Mariupol by saying that if Russia kills civilians that could be exchanged as prisoners of war, then Ukraine cannot have any diplomatic talks with Russia afterward.
