Ukrainian Prime Minister Yulia Svyrydenko resigned on Sunday after President Volodymyr Zelenskyy announced new changes to the government, saying he offered her a new and important position, according to the Associated Press.

Zelenskyy, whose term has expired, continues to hold his post under martial law, as the constitution prohibits elections during wartime, and he has periodically reshuffled his government to inject new momentum into his administration.

Svyrydenko previously served as Minister of Economy and was appointed prime minister in July 2025 at the age of 39, after playing a key role in brokering the minerals agreement between Ukraine and the United States, seen as an important way to tie U.S. interests to Ukraine's security.

In a statement on social media, Svyrydenko said she was "proud of the honor of leading the government during one of the most difficult periods in modern Ukrainian history."

She added that she discussed "next steps" with Zelenskyy without revealing further details.

"I remain ready to serve the Ukrainian state and carry out every task aimed at strengthening Ukraine's position, defending our national interests, and bringing a just peace closer," she said.

Zelenskyy announced her resignation in a post, saying Ukraine is "changing its political strategy." He added that he offered Svyrydenko responsibility for a "new and important area" in Ukraine's relations with one of its key international partners.

"Every major file in foreign policy will be entrusted to a person with extensive experience capable of implementing what we agree on at the level of leaders and what the Ukrainian people expect," he said, referring to the upcoming government reshuffle.

The Ukrainian president added that the changes will also include senior law enforcement officials in the country.

Following the announcement, Zelenskyy held a series of meetings with a number of senior officials, including Energy Minister Denys Shmyhal, Interior Minister Ihor Klymenko, and Defense Minister Mykhailo Fedorov.

This reshuffle, the details of which Zelenskyy has not yet explained, is the fourth major restructuring of his government since the start of Russia's full-scale invasion of Ukraine.

Targeting Russian Oil Sites

In a separate development, local officials said on Sunday that a Ukrainian attack in southwestern Russia killed one person and injured three others, as Kyiv continues to target Russian oil facilities.

Samara region governor Vyacheslav Fedorishchev said the injured included a child, adding that the attack damaged homes and residential buildings, as well as an unspecified industrial site.

Russian media reported that the attack targeted the Syzran oil refinery in the region, and published images showing, apparently, columns of black smoke rising above the site.

The refinery, owned by the oil and gas giant Rosneft, is located about 800 kilometers east of the border and has been a frequent target of Ukrainian attacks.

Meanwhile, Rostov region governor Yuri Slyusar said a tanker was damaged in a drone attack on the Azov-Black Sea shipping canal. He added that the tanker was empty and there was no risk of an oil spill.

Fuel Crisis

Ukrainian drone strikes on oil refineries and other infrastructure inside Russia have led to a widespread fuel crisis, with gasoline shortages and rationing in several regions, and drivers forced to wait hours to refuel.

Moscow responded by intensifying its shelling of Kyiv and other Ukrainian cities, exposing Ukraine's vulnerability to ballistic missile attacks.

Zelenskyy described the strikes targeting energy infrastructure in Russia as part of Kyiv's campaign of "long-range sanctions" in response to Moscow's refusal to end its ongoing four-year invasion of its neighbor.

In response, the Russian Defense Ministry announced on Sunday that it carried out attacks on the ports of Odesa and Chornomorsk in Ukraine's Odesa region, while Ukrainian officials did not immediately comment on the claims.
