India has accused "foreign individuals" and celebrities of "sensationalism" after a tweet by pop superstar Rihanna, extending support to protesting farmers, drew global attention.

Axar.az reports that hours after the singer's tweet, teenage climate activist Greta Thunberg and the US vice president's niece Meena Harris also tweeted support for the farmers.

Their widely shared tweets went viral, garnering thousands of responses.

Farmers have been protesting at Delhi's borders against new farm laws.

In a statement on Wednesday, India's external affairs ministry said parliament had passed "reformist legislation relating to the agricultural sector" after a full debate and discussion.

"The temptation of sensationalist social media hashtags and comments, especially when resorted to by celebrities and others, is neither accurate nor responsible," it added.
