Regional authorities said two people were killed in a drone strike on an apartment building in Kryvyi Rih, the hometown of Ukrainian President Volodymyr Zelensky, while four others died in an aerial bomb attack elsewhere in the region.

Officials said four people were wounded in the Kryvyi Rih strike, including a nine-month-old child whose leg was severed in the blast, according to regional governor Oleksandr Hanzha and military administration head Oleksandr Vilkul.Zelensky condemned the attacks in a statement posted on Telegram, describing them as “cynical and devoid of all military logic.”

“After the end of the partial three-day ceasefire, Russia continues to kill and maim Ukrainians,” Zelensky said, adding that international pressure on Moscow should not be reduced.

The truce, linked to commemorations marking the Soviet Union’s victory over Nazi Germany in World War Two, had been part of a broader U.S.-backed diplomatic effort promoted by President Donald Trump to encourage negotiations after more than four years of war.

Although both Moscow and Kyiv reported reduced large-scale aerial bombardments during the ceasefire period, each side accused the other of continued frontline shelling, drone strikes and artillery attacks.Ukrainian Foreign Minister Andrii Sybiha said Kyiv had proposed extending the ceasefire, but Russia instead intensified attacks targeting civilian infrastructure and energy facilities.

Ukraine’s air force said drones were intercepted across multiple regions overnight, though strikes still caused damage to apartment buildings, power infrastructure, a kindergarten and rail facilities.In Kyiv, falling debris from a downed drone sparked a fire on the roof of a 16-story residential building in the Obolon district, Mayor Vitali Klitschko said.

Authorities also reported injuries and infrastructure damage in the regions of Cherkasy, Zhytomyr, Chernihiv, Mykolaiv and Kherson. In the southern Mykolaiv region, governor Vitaliy Kim said drone strikes on energy infrastructure caused localized blackouts.

Zelensky said Ukrainian forces had meanwhile struck gas infrastructure in Russia’s Orenburg region, more than 1,500 kilometers from the Ukrainian border, indicating Kyiv’s continued use of long-range drone operations against Russian energy assets.

The renewed attacks underscore the fragility of ceasefire efforts as diplomatic initiatives backed by Washington and European allies struggle to halt the conflict, which has increasingly evolved into a war of attrition marked by long-range missile and drone warfare.
