The reported warning from the Trump administration could weaken Ukraine’s air defences as tensions grow over attacks on Russian energy infrastructure and efforts to secure an energy ceasefire.

The administration of US President Donald Trump has warned Ukraine and European allies that Washington could suspend intelligence sharing and halt European purchases of American weapons for Kyiv if Ukraine continues deep strikes on Russian energy facilities, this is according to two European officials.

 The warnings were reportedly sent over the weekend by the State Department and Pentagon, including direct communications from the US military to Ukrainian commanders.

The reported threat comes amid growing tensions between Trump and Ukrainian President Volodymyr Zelensky over Ukraine’s attacks on Russian oil refineries.

 Trump has repeatedly called for both sides to stop targeting energy infrastructure, citing the impact of the war on global fuel prices. Rising diesel prices have also been worsened by the US war with Iran, according to the report. 

The Financial Times first reported the alleged threats to suspend intelligence sharing and weapons purchases.

On Sunday, Trump announced that Russia and Ukraine had agreed to what he called an energy ceasefire, a development that reportedly caught a source close to Zelensky by surprise. 

Zelensky subsequently said Ukraine supported the ceasefire but stressed that Russia must also honour it.

 “We are awaiting details from the American side,” he wrote on X, signalling that Kyiv was waiting for further clarification.

The potential suspension could have serious consequences for Ukraine’s ability to defend itself against Russian missile and drone attacks.

 US intelligence helps Ukrainian forces identify missile launch sites and track incoming strikes, while the NATO-coordinated Prioritised Ukraine Requirements List (PURL) enables European allies to purchase American weapons for Kyiv. 

A halt to the mechanism could further restrict supplies of Patriot interceptor missiles, which Ukraine already needs in greater numbers. 

 NATO had not reported any change to the programme over the weekend. 

The dispute threatens to deepen an already fragile relationship between Trump and Zelensky. Washington previously suspended intelligence sharing with Kyiv in March 2025 before restoring it after Ukraine accepted a proposed ceasefire during talks in Saudi Arabia.

 Trump has also recently suggested that Ukraine should replace Zelensky, adding to tensions over US efforts to negotiate with Russian President Vladimir Putin. 

As of the latest reports, the alleged threats had not resulted in a confirmed suspension of intelligence sharing or weapons procurement, and the details of the announced energy ceasefire remained unclear. 

 The immediate question is whether Washington’s pressure will persuade both sides to stop attacking energy infrastructure or further strain Ukraine’s wartime partnership with its most important military supporter.
