Which war is having the biggest impact on diesel prices - Iran or Ukraine?
BBC Verify analyzes the impact of the Ukraine and Iran conflicts on global diesel prices, noting that supply disruptions from the Gulf region due to the Iran conflict have had a more significant effect than Russian refinery attacks. The report highlights how these geopolitical tensions contribute to record-high fuel costs for consumers and supply chains.
Why it matters
Rising diesel costs directly influence global inflation and the cost of living by increasing the price of transporting essential goods.
By Ben Chu Policy and analysis correspondent, BBC Verify Published 21 minutes ago US President Donald Trump has blamed Ukraine's attacks on Russian oil refineries for the global reduction in diesel exports and the spike in prices around the world, saying President Volodymyr Zelensky "wants to make problems for the world".
"He'd better damn well stop," Trump said, before suggesting Ukraine should "get a new leader who can make a deal".

After Trump announced a controversial deal to import diesel from Russia - promising "lower prices for Americans" - BBC Verify has looked at what has been affecting supplies of the fuel in recent months and years.
