US President Donald Trump told Ukrainian President Volodymyr Zelenskyy in a Sunday phone call to cease drone and missile attacks on Russian energy infrastructure. Trump argued that the strikes exacerbate a global fuel shortage and drive up prices, focusing repeatedly on "diesel, diesel... diesel" during the conversation. In a Truth Social post, Trump stated that Russia has lost control of its diesel industry and that many refineries are temporarily out of commission, which he identified as a primary cause for the global market strain.

Zelenskyy responded that Kyiv is ready to take de-escalation steps if Russia stops targeting Ukrainian food exports and critical energy infrastructure. The two leaders agreed to meet in New York this week on the sidelines of the UN General Assembly to discuss diplomatic momentum and a potential peace track. US diesel prices hit a record $6.51 per gallon, up 76% from $3.70 a year ago, according to AAA data.
