There is definitely evidence of a massacre near the border. There is a very good chance that many children are among the dead. That is horrible enough news.
Maybe the beheading stuff is real, but it's odd that Israel isn't confirming and more or less letting rumors take a life of their own. There is always this kind of stuff happening during wars to gain public support. JPhillips mentioned the baby incubators in Kuwait.
It's a way of dehumanizing your enemy more and covering for atrocities your own side commits. The argument of "both sides are killing innocent children, but the one side does it in a more barbaric manner" works on the public.
There is some good news I guess. The one woman who was at the rave and shown in the back of a pickup truck is apparently alive and in a hospital. Hopefully the German government can work on bringing her home safely.
