WASHINGTON — President Donald Trump said Sunday that Russia and Ukraine had agreed to an immediate “Energy ceasefire” halting attacks on each other’s energy infrastructure, but continued Russian strikes reported by Ukrainian officials raised doubts about whether the proposed truce had taken effect.

Trump announced the agreement in a brief social media post without identifying its terms, duration or enforcement mechanism. He wrote that the ceasefire was effective immediately and warned both countries, “Do not break it!”

Neither the Kremlin nor Ukrainian officials immediately confirmed that a finalized agreement was in place. Ukrainian President Volodymyr Zelenskyy welcomed the announcement but said Russian drones and bombs continued targeting Ukrainian infrastructure, including a power plant in the northeastern city of Kharkiv.

The conflicting accounts highlighted the challenges facing efforts to limit attacks on energy facilities during the war, which began with Russia’s full-scale invasion of Ukraine in February 2022. Such attacks threaten electricity supplies, heating systems and other essential services as winter approaches.

Kharkiv Power Plant Hit After Trump’s Announcement

Zelenskyy said Russian drones, including Iranian-designed Shahed-type weapons used by Moscow, continued flying over Ukraine throughout Sunday. He also reported glide-bomb attacks and strikes against energy infrastructure.

A power plant in Kharkiv was attacked Sunday evening, according to the Ukrainian president’s office, after Trump announced the proposed ceasefire.

Zelenskyy said Ukraine was prepared to stop attacking Russian energy facilities if Moscow demonstrated the same willingness.

“Ukraine supports the ceasefire, and it is important that Russia support it as well,” Zelenskyy said in a statement. He added that Kyiv was awaiting details from Washington.

The Ukrainian government has repeatedly accused Russia of deliberately targeting power generation facilities, electrical substations and other critical infrastructure to undermine civilian morale and disrupt daily life.

Ukrainian officials have described the strategy as “weaponizing winter,” arguing that attacks on electricity and heating systems are intended to increase pressure on the population by making homes, hospitals and public services harder to operate during freezing weather.

An effective energy truce could reduce those risks, but its success would depend on clearly defined restrictions, reciprocal compliance and a way to determine responsibility when attacks occur.

A Previous Proposal Failed to Produce a Truce

Trump made a similar announcement Sept. 14, saying Russia and Ukraine had agreed not to attack each other’s energy infrastructure. That proposal did not produce a sustained halt in strikes.

Zelenskyy had said Ukraine was willing to comply if Russia did the same, but no publicly confirmed agreement emerged.

The latest announcement followed renewed Ukrainian attacks on Russian oil refineries and other infrastructure, as Washington pressed Kyiv to stop strikes that could disrupt Russian fuel production.

In an interview broadcast Sunday on ABC’s “This Week,” Zelenskyy said Ukraine was ready to halt attacks on Russian refineries if Moscow stopped targeting Ukraine’s energy system. He urged Trump to deliver that message directly to the Kremlin.

The competing proposals reflect a broader disagreement over the scope of a potential ceasefire. Ukraine wants protection for its electricity grid and other essential facilities, while Russia has faced pressure to limit the damage caused by Ukrainian long-range drone operations.

Without an agreed list of protected facilities, a monitoring arrangement and procedures for investigating alleged violations, the two sides could continue disputing whether particular attacks breach a truce.

Trump and Zelenskyy Agree on Energy Ceasefire on Infrastructure

The ceasefire announcement came amid escalating tensions between Trump and Zelenskyy.

Trump said Saturday that Ukraine should get a new president, suggesting Zelenskyy had failed to do enough to end the war. Trump also blamed Ukraine for high diesel prices in the United States.

Zelenskyy responded by saying Ukraine could organize presidential elections if Russia agreed to a 60-day, nationwide ceasefire.

“Give us two months, 60 days off. Total ceasefire, 60 days, and we will organize elections,” Zelenskyy said.

He stressed that choosing Ukraine’s leadership was a decision for Ukrainian citizens.

Ukraine has been under martial law since Russia’s full-scale invasion began in February 2022. The country’s Constitution prohibits national elections while martial law remains in effect, and Zelenskyy’s presidential term formally expired in May 2024.

However, the Constitution provides for the president to remain in office until a successor is sworn in.

Organizing an election during the war would present substantial logistical and security challenges. Roughly one-fifth of Ukraine’s territory is under Russian occupation, millions of Ukrainians have been displaced abroad, and military personnel remain deployed along the front line. Authorities would also need to protect polling stations and ensure that citizens could vote without fear of attack.

A temporary halt in attacks on energy infrastructure would not, by itself, resolve those broader obstacles.

Ukrainian Drone Strikes Disrupt Russian Technology Services

While diplomatic efforts continued, Ukraine maintained its campaign against Russian infrastructure.

A Ukrainian drone strike Sunday shut down a data center operated by Yandex in the Russian city of Vladimir, east of Moscow, according to Russian reports and the company’s service-status channel.

The incident was the third reported strike on Yandex facilities in four days.

The data center’s shutdown disrupted services used by customers in Russia and neighboring countries, including Kazakhstan, Belarus and Armenia, according to the independent Russian news outlet Astra.

Yandex Data Center Impacted

Yandex, often described as Russia’s equivalent of Google, operates the country’s leading search engine and a broad range of online services, including transportation, shopping, cloud computing and financial technology.

The company’s cloud-service channel said operations at the affected data center had stopped completely but reported no injuries.

Users described difficulties ordering taxis, contacting drivers and accessing online shopping services. The disruption illustrated how attacks on digital infrastructure can affect ordinary activities even when the immediate target is not a power plant or fuel facility.

Earlier in the week, drones struck Yandex facilities in the Ryazan and Kaluga regions, according to reports. The incidents added to concerns about the vulnerability of infrastructure that supports both commercial services and broader economic activity.

Deadly Bombing Despite Energy CeaseFire Adds to Civilian Toll

The latest diplomatic developments also unfolded amid deadly attacks on civilians.

Search and rescue operations ended in the southern Ukrainian city of Zaporizhzhia following a Russian bombing Saturday. Zelenskyy said 23 people were killed, including four children, while regional officials reported more than 30 wounded.

Eight injured people remained hospitalized, according to Ivan Fedorov, a former regional head and co-chair of the regional defense council.

Separately, a Ukrainian drone strike in Russia’s Bryansk border region killed a man and wounded two women, local officials said Sunday.

The reported casualties underscored the continuing human cost of the conflict despite renewed discussion of limited ceasefires.

Energy Security Remains Central to Peace Efforts

Energy infrastructure has become a major target in the war because damage to refineries, power stations, pipelines and electrical networks can affect military logistics, industrial production and civilian life.

For Ukraine, Russian attacks threaten the electricity and heating systems needed to sustain communities through winter. For Russia, Ukrainian strikes on refineries and other facilities can disrupt fuel production and impose economic costs.

Trump’s proposed ceasefire could provide a limited step toward reducing those risks if both governments accept and observe its terms. But the absence of publicly established details, combined with reports of continued attacks, left the status of the agreement uncertain Sunday.

For now, Ukraine says it is willing to stop striking Russian energy infrastructure if Russia does the same. Whether Moscow will formally commit to that arrangement remains a central question for Washington’s diplomatic efforts.

A verified halt to attacks on energy facilities would not end the war, but it could offer civilians some protection from one of its most damaging dimensions. Until the two sides establish clear rules and demonstrate compliance, the proposed truce remains an unproven test of whether limited cooperation is possible amid continuing hostilities.
