Russian Ministry of Defence: On 25 September, an air-launched cruise missile carried out a precision strike on a joint arms and ammunition depot of the Ukrainian armed forces near the village of #Kiselevka in the #Kherson region. As a result of the strike and subsequent detonation, 12 hangars containing more than three thousand tonnes of ammunition of various calibres were destroyed.
That sounds a lot but it's Russian source so it's over estimated a lot. But watching the video, it looked like a pretty big explosion (after impact).
