Two spectators sustained grave injuries after one of the pair of Ka-52 attack helicopters flying in an attack formation accidentally fired S-8 rockets toward the crowd that gathered at the Luzhsky training ground near St. Petersburg. The footage shows two Kamov Ka-52 helicopters approaching what is probably a range, where a group of several cars is parked. the clip, that leaked online on Sept. 19, was allegedly filmed during the ongoing Zapad 2017 drills; however the Russian military denied the claims that spread through the social media and, while not saying when and where it happened, it said the incident happened during another exercise.
