The intentional nature of the disaster is not an established and proven fact. It suits Ukrainian narrative of painting everything that Russia does as yet another heinous genocidal act, but at least in some cases (including this one) negligence is also a plausible explanation (i.e. it could happen because of not paying enough attention to maintenance and stocking ammunition where it should not be) [1]. This of course does not remove responsibility from Russia: even if in a very unlikely scenario it was sabotaged by Ukraine as Russia claims, it would not happen if Russia has not invaded Ukraine. Still it is important to have an objective view on the events to make sure that real crimes get enough attention from the public and that proper investigation of the events is done.
That said, given that we do not have yet a better understanding of what has happened, the headline is accurate enough and complaints about it look like pro-Ukrainian propaganda rather than an attempt to share the truth.
