Child abuse or just baby yoga?
Warning: Disturbing images
A video showing a baby being swung around in a bucket of water and held upside from the legs has gone viral on Facebook.
Charities in the UK have been calling for the social media giant to remove the clip, which they say shows torture and abuse of a child.
But Facebook said the video shows "baby yoga" and is not against its policies.
Its spokesman told Daily Star Online: "We do not allow child abuse on Facebook and any illegal content which is flagged to us is quickly removed.
"Whilst we understand that people may be upset by this video which depicts a form of baby yoga, after careful review we found it does not break our rules."
The video is believed to have originated from Indonesia, reported UK media.
In the video, which is almost two minutes long, the baby screams as he/she is swung around by his/her hands.
The baby is then held upside down by the legs.
The baby is made to jump up and down as the woman tugs on his/her arms.
By the end of the video, the child is silent.
Mail Online quoted Ms Lurleen Hilliard, founder of Nolonger Victims, a charity campaigning against abuse, as saying: "It’s one of the sickest videos I’ve ever seen in my life.
"At the very minimum that baby is brain damaged from the shaking."
Said Ms Gabrielle Shaw, chief executive of UK charity National Association for People Abused in Childhood: "To dismiss this video of a screaming baby being violently shaken and manipulated in a tub of water, as a form of 'baby yoga'.
"The fact that Facebook has reviewed it and allowed it to stand, is staggering."
