A Russian drone strike on a warehouse in Mila, west of Ukraine’s capital Kyiv, killed at least 27 people, according to the source. The attack triggered a fire at the facility, followed by a series of explosions. Ukrainian prosecutors said they believe explosive materials had been stored at the site.

Kyiv regional governor Timur Tkachenko said the death toll could rise. Among those killed was Taras Didych, the mayor of Dmytrivska village. The source did not provide a date for the attack or further details about the people injured.

Ukraine’s Prosecutor General’s Office has opened a criminal investigation into the incident. Investigators are examining whether storing explosive materials at the warehouse was legal and whether the relevant organization had the required permits. The report comes as Russia and Ukraine have intensified long-range strikes on each other’s territory in recent months.
