Regional Governor Veniamin Kondratyev said 40 people were injured in the incident, with 17 victims requiring hospital treatment, according to the BBC.

At least seven people, including three children, were killed after a drone crashed onto a crowded beach in Russia's southern Krasnodar region, triggering a massive explosion that also left dozens injured in one of the deadliest incidents involving civilians on Russian territory in recent months.

The attack occurred at a beach near the Black Sea resort village of Arkhipo-Osipovka, where holidaymakers had gathered during the peak tourist season.

Regional Governor Veniamin Kondratyev said 40 people were injured in the incident, with 17 victims requiring hospital treatment, according to the BBC.

The drone reportedly flew toward a cliff before plunging onto the beach, where it exploded in a fireball as people watched from the shoreline and the sea.
