Here is a good example, one of many, which illustrates how quick and how far - up to the US president Biden - fake news can spread. A Zionist propagandist here is an Israeli soldier who also happens to be a far-right fanatical and very aggressive settler - David Ben Zion - who made a statement about children with severed heads in Kfar Aza. The story was picked up by many news outlets around the world and politicians who acted on this false claim. Later the claim was dismissed as false, but damage has been done - the world was more inclined to turn a blind eye to Israelis committing genocide in Gaza.
Also, according to wikipedia article on Kfar Aza massacre: https://en.wikipedia.org/wiki/Kfar_Aza_massacre Claims by Israeli media and government sources advancing that 40 babies had been decapitated went viral. While a massacre of civilians did occur, a few of the most lurid claims, including the baby decapitations, were later found to be false. Evidence provided by Bituah Leumi, Israel's national social security agency, showed that of the 46 civilians that were killed in Kfar Aza, the youngest was 14 years old.
The State of Israel’s official X account, with a following of 1.5 million, posted Oct. 15, "Lots of sick people fighting about whether or not Hamas beheaded 40 babies or whether they were just burned alive or just butchered. Shame on you."
An Oct. 10 TikTok video that has been viewed more than 488,000 times showed a woman crying and text that read, "40 babies. Hamas has beheaded 40 Israeli babies in a single Israeli community."
