She later added: “Please don’t tell me oh US sees shootings everyday hence no coverage. If a Muslim had shot down 3 people it would be everywhere.”
Nejer wrote: “This is horrific and the fact that big media and news outlets are not paying attention makes it even worse.”
AJ+ asked: “Why do you think the Chapel Hill shooting is resonating more on social media than in traditional news media?”
Some twitter users pointed to the public outcry after the Charlie Hebdo murders and asked why the shootings had not attracted similar attention.
Others accused news channels of downright Islamophobia, singling out the BBC and Fox News.
Ahmed Al Qasim tweeted: “Don’t expect much from the media as long as the killer is not Muslim.”
Amid unconfirmed reports Hicks is an atheist, author Richard Dawkins tweeted: “How could any decent person NOT condemn the vile murder of three young US Muslims in Chapel Hill?”
The hashtag #MuslimLivesMatter also trended worldwide off the back of the tragedy, questioning the lack of coverage in the media of the shooting.
Many highlighted the subjects the media were covering in favour of the incident.
Muslims expressed strong feelings of alienation and victimisation.
