United States President Donald Trump said that he would be ready to send Ukraine long-range Tomahawk missiles if the war with Russia remained unresolved, Azernews reports.

While boarding Air Force One on his way to the Gaza peace conference, Trump said that he told Ukrainian President Volodymyr Zelensky that he would tell Russian President Vladimir Putin that he would supply Ukraine with Tomahawk missiles if the war remained unresolved.

Writing on X, the Ukrainian president called his latest conversation with Trump “very productive”, noting that they had discussed strengthening his country’s “air defence, resilience, and long-range capabilities”. It was the second time the pair had spoken in as many days.

On Monday, Trump said he would only agree to provide Kyiv with Tomahawks if he knew what it planned to do with them. He added, without giving further details, that he had “sort of made a decision” over the issue.

Given that their range is 2,500km (1,550 miles), Ukraine could use the weapons to strike deep inside Russia.

In comments published on Sunday, Kremlin spokesperson Dmitry Peskov said the topic was of “extreme concern” to Russia.

“Now is really a very dramatic moment in terms of the fact that tensions are escalating from all sides,” he told Russian state television reporter Pavel Zarubin.

Peskov said Moscow would have to bear in mind that some versions of the missile are able to carry nuclear warheads.

The Kremlin spokesperson’s remarks came as French President Emmanuel Macron condemned the latest Russian strikes on Ukraine’s energy infrastructure.

After speaking with Zelenskyy on Sunday, Macron said: “As the agreement reached in Gaza offers a glimmer of hope for peace in the Middle East, the war in Ukraine too must come to an end.”

“If Russia persists in its obstinate warmongering and its refusal to come to the negotiating table, it will have to pay the price,” he said.
