Is that from a reliable source? I see three versions of that story on the web, all with the same repetitive language and no details. None have basic information like When? Where? Who reported and confirmed? How huge?
That's a photo of a drone with what might be a grenade, dropped over a collage of unrelated photos. This has the look of a typical internet hoax.
How likely is it that a "huge ammunition depot" could be destroyed with a single grenade? How many Black personnel does Ukraine's military have? Do the sand dunes in the background look like a Ukrainian landscape?
The author is listed as Jessika Muscat. The only Jessika Muscat I can find on the web is a singer/actress from Malta.
