Zelensky Says Western Allies Must Allow Ukrainian Strikes Deep Into Russia

President Volodymyr Zelensky of Ukraine said Tuesday that he would urge the leaders of the United States, Britain and France to allow Ukrainian forces to use weapons supplied by those nations for strikes deep into Russian territory.

Mr. Zelensky said he had yet to get permission from any of those countries, despite other NATO leaders arguing that Ukraine should be given leeway for broad use of missiles and other arms supplied by its partners.

Mr. Zelensky said he would make his case this week in meetings with President Biden and in a separate meeting with Keir Starmer, the prime minister of Britain, and Emmanuel Macron, the president of France.

“Our decision depends on their will,” he said in an interview with The New York Times on Tuesday morning at the United Nations with Mette Frederiksen, the prime minister of Denmark. “For today, they have to give, or say that they will not give.”

“Do they really want us to prevail, or is it about something long, some terrible and long tragedy?” Mr. Zelensky said.

Recent diplomatic discussions among the three allied nations have focused on the question of allowing Ukraine to use imported weapons for long-range fire into Russia. Mr. Starmer and Mr. Macron are leaning toward giving permission but want to coordinate with Mr. Biden, who could soon decide to support Britain and France in loosening their restrictions before the United States does anything similar, U.S. officials say.
