Conflicting dates indicate that the beheading of Rehana is suspect. The Daily Mail is the only news outlet to break the story, which raises questions about the reliability of the source.
A google search on the topic of ‘Rehana beheaded’ results bring up a graphic image that appears to be an ISIS member holding up the severed head of what appears to be Rehana.
Looking at when the first picture of the beheading was published, a google image search puts the earliest publication of the picture the 6th October. But the iconic picture of Rehana throwing a peace sign was published after this date. The conflict in dates indicates that this cannot be the proof of Rehana’s alleged beheading.
