Faked images showing the Parkland school shooting survivor Emma Gonzalez tearing up the US constitution have emerged on social media.

The images were doctored from a photo shoot the 18-year-old did showing her tearing up a shooting target as part of her gun control campaign.

The incident is not the first time survivors of the mass shooting, who have since become prominent campaigners for gun control, have been targets of fake news and it has led to calls for Twitter CEO Jack Dorsey to take action.

The false images and gifs come as the 18-year-old led protestors at the March For Our Lives rally over the weekend, which saw hundreds of thousands of people descend on Washington D.C. in one of the biggest demonstrations since the Vietnam War era.

The doctored images and clips of Gonzalez were based on a gif that appeared on Teen Vogue’s Instagram account showing her surrounded by other Parkland students as she tore a shooting practice target in half.
