A massive crowd of farmers and farm workers gathered in India's northern Punjab state on Sunday in a show of strength against new farm laws.

Up to 130,000 protesting farmers and farm workers gathered in India's Punjab state on Sunday, according to police estimates.

Both sides have met for several rounds of negotiations but failed to make any headway. Farmers' unions have vowed to carry on the protests until the laws are rolled back.

At Sunday's rally at a grain market in Barnala, a town in Punjab, union leaders outlined plans to mobilize farmers from across the state and move to a protest site outside Delhi later this month.
