The protests were called by the Opposition Left Front, the Samajwadi Party, the Rashtriya Janata Dal (RJD), the Biju Janata Dal (BJD) and the AIADMK .
They were demanding a rollback in the prices of fuels, fertilisers and other commodities in a bid to bring down food inflation that has soared in recent months.
The Bharatiya Janata Party (BJP)-led National Democratic Alliance (NDA) stayed away from the event.
