Twitter has lost legal immunity over content posted by users in India.

That's according to High Court filings.

And the news could threaten its ability to keep operating in the country.

India's government says the social media giant has failed to comply with new IT rules.

Now the court papers are the first official confirmation that Twitter has lost its immunity, though ministers have repeatedly criticised the firm for non-compliance.

Twitter hasn't commented on the news, saying previously that it had made all possible efforts to comply.

Recent weeks have seen Indian police file at least five cases against Twitter or its employees.

The state of Uttar Pradesh has gone to the Supreme Court to challenge a bar on action against Twitter India boss Manish Maheshwari.

A lower court had given him protection against arrest over an allegation that Twitter was used to spread hate.
