Britain First have posted a shocking video of Muslim women being auctioned off in the streets of London.
Only it isn't.
It is in fact a video of a mock 'Islamic State sex slave market' staged by Kurdish activists in 2014.
The group Compassion 4 Kurdistan were responsible for the stunt which saw a man declare: "We have four women for you here today and we are here to sell them courtesy of the Islamic State."
Actual facts didn't stop Britain First's supporters showing their utter disgust with their perceived state of the capital.
Thankfully, not everyone was fooled.
One of the people behind the protest told Newsweek Europe in 2014 that the protest was carried out to spark an “aggravated reaction,” highlighting the “crimes ISIS are committing in Iraq and Syria.”
“What we wanted to show is that this could take place in London,” he said.
The issue of sex slaves trafficked by so-called Islamic State is harrowingly real - just not in London.
Islamic State fighters have captured, enslaved and sold Yazidi women and children, and claim the act is justified in Islam to prevent men from feeling “tempted” by other, non-enslaved women.
According to a piece in the Islamic State’s full-colour magazine, which is published in English and evidently aimed at a Western audience, confirms the long-rumoured atrocities committed by the group in Iraq, where Yazidi women have reported being kidnapped, sold for a few dollars and repeatedly raped.
An issue of Dabiq magazine released around the time of the protest stated, “the enslaved Yazidi families are now sold by the Islamic State soldiers.” It added, “the Yazidi women and children were then divided according to the Sharia amongst the fighters of the Islamic State who participated in the Sinjar operations.”
