Ukrainian President Volodymyr Zelenskyy urged the international community on Thursday to block seaborne Russian exports, singling out oil tankers in particular.

“No Russian ship should have a possibility of entering any port in the democratic world,” Zelenskyy told Greek lawmakers.

“Why should we help them so that they make even more money by and for producing their missiles and bombs to destroy not only Mariupol but also other Ukrainian cities?”, he said in his address broadcast live via teleconference.
