President Volodymyr Zelensky said the blast damaged residential buildings and a care home in the surrounding area, with an investigation launched into whether ammunition was being stored on site. Four children are among 42 people injured, according to regional head Tymur Tkachenko, with search and rescue operations ongoing at the site in the Bucha district on Saturday. Zelensky wrote on X: "The regulations are clear: Ammunition must not be stored near houses or other residential buildings. Appropriate conclusions will certainly be drawn." He said more than 300 emergency service personnel had been deployed to the village of Myla, where "a care home for elderly people and people with disabilities" was among the properties damaged. "Criminal proceedings have been opened on charges of official negligence," he said. The office of Ukraine's prosecutor general said it was reviewing the "legality of the placement and storage of explosive objects and materials" near residential buildings. It said the "actions of officials who made the relevant decisions" would also be investigated. Russia's Ministry of Defence said in a statement that its forces had targeted "an ammunition depot" in Myla which stored "components and launch boosters for FP-1/FP-2 long-range unmanned aerial vehicles".
