After verifying the facts, hibrid.info has confirmed that the TikTok account "lumjanana009" has raised a false claim about the departure of 40 thousand Serbs from Mitrovica over the last two days, using photographs of events from 1999 and 2021.
Based on its work methodology, hibrid.info assesses this video material as "Fake News".
Reasoning:
The "Fake News" rating is given to media reports that are entirely the product of a medium that itself contains factually incorrect claims or information.
Content that is considered fake news can be reliably determined to have been created and distributed with the intent to misinform the public, i.e., to present a claim that is completely false as fact.
