'Criminal negligence' — PM Koretskyi demands accountability after Russian attack injures 6, sparks fires and detonations near Kyiv

"On the fifth year of the full-scale invasion, making the same mistakes is criminal negligence," Koretskyi said in a statement posted on Telegram. "And all those responsible, without exception, must face severe punishment so that such situations do not happen again."

Kyiv Oblast Governor Tymur Tkachenko said there had been fatalities as a result of the attack, though the final death toll is yet unknown. Rescuers and other emergency services are continuing to work at the site, he added.

A response command post has been deployed at the site of the attack in the Bucha district, Tkachenko said earlier, with rescuers, police, medics, and other emergency personnel working to eliminate the consequences of the strike. More than 200 people, including children, had been evacuated from the site.

Koretskyi said he had received reports from the interior minister and the head of Ukraine's State Emergency Service about the attack in the Bucha district, where a fire broke out after the site was struck and was followed by detonations.

According to the Prosecutor General's Office, prosecutors have opened a pretrial investigation into Russia's conduct of the war and possible official negligence in the attack.

Prosecutors said the investigation will examine not only the circumstances of the Russian attack but also "the causes and conditions that could have significantly worsened its consequences."

In particular, investigators will examine whether the storage and presence of explosive materials at the facility were lawful, whether the necessary permits and approvals were obtained, and the actions of officials who made the relevant decisions, the Prosecutor General's Office said.

"Unfortunately, we can already state that the terrible tragedy in Vyshneve did not become a lesson," Koretskyi added.

On July 6, a Russian drone and missile attack struck an ammunition depot operated by Ukraine's state-owned defense conglomerate Ukroboronprom in Vyshneve, triggering powerful secondary explosions. Seven people were killed, and 29 were injured.

Ukraine's Security Service later identified the heads of two state-owned enterprises within Ukroboronprom as primarily responsible for violating ammunition storage regulations.

The latest attack also prompted the closure of a section of the M-06 Kyiv-Chop highway, a major route connecting Kyiv with western Ukraine, between the 15th and 32nd kilometers, Tkachenko said earlier. Warehouse facilities were burning in the Bucha district, and the fire was accompanied by explosions, he said.

Emergency services are working to contain the fire, while Ukraine's Patrol Police published alternative routes for drivers.
