Ukrainian President Volodymyr Zelenskyy indicated backing for the energy ceasefire arrangement announced by U.S. President Donald Trump on Sunday, with Zelenskyy's social media post framing his country's position as one of consistent readiness to support any measures aimed at reducing hostilities, protecting lives, and moving toward a durable end to the conflict.

Zelenskyy reported holding talks on the ceasefire with Canadian Prime Minister Mark Carney, Finnish President Alexander Stubb, and NATO Secretary General Mark Rutte. Awaiting further details from the United States, Zelenskyy stated that Ukraine backs the ceasefire arrangement and called on Russia to do the same. Trump had posted an announcement about the ceasefire on Truth Social that Sunday morning without providing specifics.

Trump's post stated that a ceasefire had taken effect immediately, with both Ukraine and Russia having agreed to its terms, accompanied by a written directive that the truce hold. No elaboration on the post was forthcoming from the White House, which left the statement without further context or detail.

Speaking on a broadcast that aired Sunday, Zelenskyy put forward a conditional position: Ukraine would halt its strikes on Russian oil refineries provided Moscow brought its own attacks on Ukraine's energy infrastructure to a stop. Zelenskyy also put a request to Trump that he use his influence with the Kremlin to bring about an agreement.

Speaking at the weekend, Trump called for a change in Ukrainian leadership and attributed the rise in diesel prices to Zelenskyy. Zelenskyy indicated that elections could take place if Russia agreed to a 60-day pause in hostilities — a threshold tied to the constitutional bar on voting while martial law, in effect since Russia's 2022 invasion, remains active. While acknowledging Trump's interest in the matter, Zelenskyy noted that the choice of leadership ultimately rests with Ukrainian society itself.

Separately, a drone strike attributed to Kyiv on Sunday knocked out a data centre operated by Russian technology company Yandex, deep within Russian territory. The company's facilities have now been targeted on three separate occasions within a four-day span. Service disruptions spread across dozens of Russian cities and extended into Kazakhstan, Belarus, and Armenia following the incident, a Russian news outlet reported. Yandex reported that all activity at the site had been brought to a full stop and that no one was hurt.

On Thursday, a drone impact was reported at a Yandex data facility located in the Ryazan region, an area lying to the southeast of Moscow. The following day, drone strikes attributed to Ukraine brought down systems at the firm's data facility in the Kaluga region, an area lying to the southwest of Moscow. Among Russian technology companies, Yandex holds the dominant position in internet search and plays a central role in the country's push to develop artificial intelligence.

Zelenskyy announced that crews in the southern city of Zaporizhzhia had concluded search and rescue work following an attack by Russian forces the previous Saturday. Forty-six people lost their lives when the assault took place, among them four children, according to official accounts. Injuries were recorded among at least 30 individuals.
