US threatens to block weapons deliveries to Ukraine if Kyiv keeps striking Russian oil refineries

The Financial Times reports that the administration of US President Donald Trump wants Ukraine to halt its attacks on Russia's energy system, including oil refineries. The newspaper attributes the information to European officials. It matters because Ukraine relies heavily on foreign weapons deliveries to defend itself against Russia's invasion.

According to the report, Washington is using blunt threats to achieve this aim. The mechanism through which Kyiv receives American weapons could be jeopardised. The source gives no further details on how this mechanism works or what specific steps might be taken.

The report rests on the Financial Times citing unnamed European officials, and the source text does not include official confirmation from either the US or Ukraine.
