A drone hit a busy beach in southern Russia, killing seven people including three children, local authorities have said, BBC reported. 

In social media footage verified by the BBC, a drone can be seen hurtling towards a cliffside before crashing into a fireball on the beach below as tourists look on from the shore and in the water.

The total number of injured reached 40, with 17 people hospitalised, said the governor of the Krasnodar region Veniamin Kondratyev.
