Here's an example of Propaganda wars at work.
Back in March "Ukraine officials" claimed Russia was using widely-banned butterfly mines.
This was decried in Western headlines at the time.
However, a well-known German news organisation, Deutsche Welle, then de-bunked this after finding no evidence at all of their use - not one picture, social media post, or similar report.
Fast forward several months and now social media is flooded with actual reports and images of thousands of Butterfly mines appearing over civilian neighbourhoods in Russian-controlled Donetsk.
While this featured prominently in Russian news, perhaps as the alleged perpetrator is the Ukraine side, it was mostly ignored in Western media.
Asked who might be responsible for dropping the mines, Human Rights Watch stated "we are not commenting... at this point since it is impossible to independently verify or attribute the reporting."
The UDF speculated the Russian/Separatist side peppered their own people with mines.
"British Intelligence" may agree as today they flipped the script:
"Russia likely trying to use ‘deeply controversial, indiscriminate’ mines in Ukraine: UK intelligence"
But reading into the article... "The U.K. Ministry of Defence didn’t cite sources in its intelligence report..."
Taking their cue, the Daily Mail gets in on the action. Only now the Russians are not "likely trying", they ARE using Butterfly mines:
"Russian forces are using deadly butterfly mines in Donbas that maim children who mistake them for toys, Britain’s MoD warns"
However, the Daily Mail article also makes no mention of where and when and cites no source than the UK MOD's speculation.
And thus, "evidence" is born...
