A Russian drone attack on a major dairy production facility in Ukraine’s Kyiv region has left four workers dead and several others injured after a devastating strike triggered a large fire and partial building collapse.

The attack hit a factory operated by Yagotynske in the Brovary district while employees were on duty, The Caspian Post reports via RBC-Ukraine.

The strike sparked a massive blaze in the administrative section of the facility, with emergency responders racing to the scene to search through smoke-filled rubble. Rescue teams managed to pull two survivors from the wreckage, while the death toll rose from an initial one fatality to four as recovery operations continued.

Photos released by Ukraine’s State Emergency Service show extensive destruction at the site, with damaged structures and firefighters working amid debris.

The factory strike came during a large-scale Russian aerial assault involving more than 200 drones and guided missiles launched across Ukraine. Ukrainian officials said air defenses intercepted most of the incoming drones, but several targets were still hit, causing damage and casualties.
