The track called 'Zayn Did 9/11' features the singer's silhouette superimposed over an image of the September 11 attacks, reported Daily Mirror.
Fans are petitioning to have the offensive song 'Zayn Did 9/11', which includes a picture of the Twin Tower attacks and the singer's silhouette, removed from iTunes
The hugely offensive track is still available to download from the official iTunes store and an online petition to have it removed already has more than 200 signatures.
It's claimed to be the work of American rapper Rucka Rucka Ali. His Twitter account has since been suspended but the song itself remains free to play on YouTube.
