Russian attacks on critical infrastructure disrupted electricity and water supplies in Kyiv and surrounding areas on Wednesday, while rescue workers continued searching for survivors in southern Ukraine following a deadly strike that killed at least 37 people.
On Monday, Russian guided bombs hit a school and an underground shelter in the frontline village of Komyshuvakha in the Zaporizhzhia region. Authorities said around 38 people might still be trapped beneath the rubble.
In Kyiv, residents were advised to collect drinking water from public fountains, while emergency centres were opened in badly affected neighbourhoods to provide hot drinks and charging facilities.
State-owned electricity operator Ukrenergo said Russian forces had attacked energy facilities more than 20 times within 24 hours. Strikes on power plants and substations across nine regions on Tuesday caused outages in and around the capital.
Meanwhile, representatives from the United States, Germany, France, Britain, NATO and the European Union were scheduled to meet in Brussels to discuss Ukraine's post-war security arrangements, reconstruction and economic opportunities ahead of another round of US-mediated peace talks next week.
The death toll from Monday's attack in Komyshuvakha reached 37, acting regional military administration chief Mykhailo Semikin said.
Regional defence council co-chair Ivan Fedorov said 12 recovered bodies had been identified, while around 38 people were believed to remain under the debris. Authorities could not confirm whether anyone was still alive.
Ukraine's National Police said some victims could not be identified visually, prompting specialists to collect DNA samples from relatives.
Baptist pastor Vladyslav Makhovskyi, who joined the rescue operation, said many people were likely killed immediately, while others may have suffocated beneath the rubble.
Separately, Ukrainian President Volodymyr Zelenskyy awarded US First Lady Melania Trump the Order of Princess Olga, First Class, recognising her humanitarian contribution to Ukraine and support for children.
The award also acknowledged her role in helping secure a six-day ceasefire that facilitated evacuations from Russian-occupied Oleshky.
Meanwhile, Russia's Defence Ministry claimed its air defences had destroyed 709 Ukrainian drones overnight. Online retailer Ozon reported a fire at its logistics centre in Adygeysk following a drone attack, with no casualties reported.
