Volodymyr Zelensky called on the United Nations and world powers to come to his aid, as he has in a series of other addresses given around the world since the start of the war Feb. 24. He compared Russia’s destruction of the port city of Mariupol to the Syrian and Russian destruction wrought on the city of Aleppo in the Syrian war.

"They are destroying our ports,” Zelensky said. "The absence of exports from Ukraine will deal a blow to countries worldwide.”

Zelensky called on countries to increase their exports of energy — something particularly important as Qatar is a world leader in the export of natural gas. Western sanctions have deeply cut into Russian exports, which are crucial for European nations.

Also on hand was Saudi Foreign Minister Prince Faisal Bin Farhan, the top diplomat for the world's biggest oil exporter. Saudi Arabia so far has said it would stick with an OPEC+ production schedule the cartel struck with Russia and other producers.

Zelensky criticised Russia for what he described as threatening the world with its nuclear weapons, raising the possibility of tactical nuclear weapons being used on the battlefield, according to the Associated Press.

"Russia is deliberating bragging they can destroy with nuclear weapons, not only a certain country but the entire planet,” Zelensky said.

He also noted that Muslims in Ukraine would have to fight during the upcoming holy fasting month of Ramadan.

"We have to ensure this sacred month of Ramadan is not overshadowed by the misery of people in Ukraine,” he said.
