UN experts have called for an independent investigation into Indian authorities' conduct in a recent crackdown on protests, where they said demonstrators had sustained injuries and faced ill-treatment.

The protest crackdown has been condemned by human rights groups like Amnesty International and Human Rights Watch.

Opposition political parties and student organizations have held protests this month in India demanding Chief Election Commissioner Gyanesh Kumar's resignation over a revision of voter lists that they say favors Prime Minister Narendra Modi's Bharatiya Janata Party.
