"Explosion rocks Vladivostok, unidentified flying object spotted"

From yahoo.com via "The New Voice of Ukraine" | August 9, 2023.

"An explosion rocked the Russian city of Vladivostok near a naval base on Aug. 9, and a video showing a flying object hovering for an extended period in the area has gone viral." 

Russian naval vessels of the Russian Pacific Fleet under attack?

"The corvette 'Gromky' of the Pacific Fleet was involved in a training exercise to defend Vladivostok from a hypothetical aerial strike by an 'adversary,' at the time, according to the press service of the Eastern Military District of the Russian Federation."

The adversary turned out to be much more than notional?

“The air defense systems of the corvette 'Gromky' identified targets, prepared the air defense for deployment, and practiced the algorithm of actions during a simulated air attack.”

SIMLATED AIR ATTACK AND NOTHING MORE THAN THAT?

Move along folks. Nothing to see here?
