KYIV — A proposed pause in Russian and Ukrainian attacks on energy infrastructure remained uncertain Monday after President Donald Trump announced an agreement that Ukraine’s president said had not been clearly defined or verified. Trump said Ukraine and Russia had agreed to stop striking energy targets. The announcement followed his criticism of Ukrainian attacks on Russian oil refineries, which he blamed for high diesel prices. Trump said the fuel costs were not primarily connected to the U.S.-Israel war on Iran. Ukrainian President Volodymyr Zelenskyy responded that Kyiv was prepared to match a genuine Russian halt but had little confidence Moscow would comply. “Ukraine is not confident that Russia has any intention of adhering to any agreement,” he wrote on X. Zelenskyy said Ukraine could stop its own attacks if international partners could establish that Russia was truly willing to refrain from targeting Ukraine’s electricity system, energy facilities, critical infrastructure and food-supply routes. He called for details from those partners before accepting the arrangement. The Ukrainian president also rejected a short-term pause that could serve Russia’s political interests or ease pressure on fuel prices without reducing the broader assault. He said any ceasefire would need to last long enough to be credible, rather than simply cover Russia’s parliamentary elections scheduled for Sept. 18 through Sept. 20. Russia has repeatedly targeted Ukrainian ports, power networks, fuel stations and logistics infrastructure with missiles and drones during the war. Ukrainian strikes on Russian energy facilities have intensified as Kyiv has sought to disrupt the infrastructure supporting Moscow’s military and economy. The Kremlin had not formally responded to Trump’s announcement as of Monday evening. Kremlin spokesman Dmitry Peskov praised Trump’s call for Ukraine to stop attacking what he described as peaceful economic infrastructure, but declined to say whether Russia would halt its own attacks on Ukrainian infrastructure if Kyiv agreed. The uncertainty echoes an earlier, U.S.-backed three-day ceasefire in May intended to cover Russia’s Victory Day celebrations. During that pause, Russia launched attacks involving 40 drones and a ballistic missile, according to the report. The dispute places the proposed truce on fragile ground. For civilians in Ukraine, any durable protection for power plants, fuel supplies and food routes could reduce the risk of blackouts and disruptions. But without clear terms, reciprocal commitments and a way to verify compliance, the announcement has yet to amount to a dependable ceasefire.
