Muslims,is it true that shia of iraq chop new born babies on the grave of husain as a sacrifice?

I heared about an incident on the time of Saddams rule there was a shia woman who brought her new born baby and put him on the grave of husain and chopped him by a sword,then Saddam ordered her and the people who shared her in this rite to be executed,among of her partners in this crime was the chief of her tribe and he also got executed.
