First came a one-minute video taken on the streets of Bucha, a Kyiv suburb abandoned by retreating Russian forces. The footage showed numerous bodies, civilians in winter coats, scattered along the muddy roads like leaves on a fall day.
It fell to Valeriia Stepaniuk, 22, to set things straight.
Stepaniuk fact-checks content for Facebook as part of her job at a think tank called VoxUkraine. After scouring credible news sources — such as a BBC article that said satellite imagery disproved Russian claims that the Bucha footage was staged — she and a handful of colleagues are compiling a report to debunk the misinformation flooding social media.
