An American woman who was in a Paris cafe in 2015 when 19 people were murdered there by ISIS terrorists is suing Facebook, Twitter and Google.

Internet technology consultant Mandy Palmucci filed the federal lawsuit - which claims the social media platforms helped the murderous group grow - last week in Chicago.

The suit says she was at La Belle Equipe cafe when 19 people were slaughtered there by Islamist terrorists.

She said she still suffers emotionally from the attacks, and still remembers the screams of victims.

Similar lawsuits elsewhere have been dismissed on grounds that laws shield online providers from responsibility for content posted by users

Her suit, which cites the Antiterrorism Act, also claims the Islamist group has about 70,000 Twitter accounts that post 90 tweets a minute

The 128-page document also contends the group uses the websites to 'specifically threaten France that it would be attacked for participating in a coalition of nations against ISIS'

The ISIS attacks on cafes, the national stadium and the Bataclan music hall left 130 people dead on November 13.

Palmucci, however, claims the growth of ISIS 'would not have been possible' without social media platforms.

Her suit, which cites the Antiterrorism Act, also claims the Islamist group has about 70,000 Twitter accounts that post 90 tweets a minute, the Chicago-Sun Times reports.

The 128-page document also contends the group uses the websites to 'specifically threaten France that it would be attacked for participating in a coalition of nations against ISIS'.

It is like used to 'celebrate smaller attacks leading up to these major attacks' and to make the Paris terrorists into 'celebrity' jihadists.

The social media platforms, meanwhile, 'routinely profit' from ISIS content, the suit alleges.

Ads, it also claims, are not 'placed randomly' alongside ISIS posts.

Facebook said in a statement there's no place on its site for those who engage in terrorism or for content that supports such activity.

It added: 'We are committed to providing a service where people feel safe when using Facebook.'

Twitter and Google did not respond to the newspaper's messages seeking comment.
