New Delhi: Tens of thousands of farmers gathered on the outskirts of New Delhi on Tuesday, ahead of a tractor procession aimed at protesting a controversial set of agricultural laws.

In one incident, thousands of farmers knocked down police barricades as they entered Delhi this morning on foot amid huge police presence ahead of the huge tractor rally.

In unprecedented visuals, chaos could be seen unfolding at the Singhu border, which divides Delhi and Haryana, and Tikri border in the western part of the national capital. Thousands were seen marching with flags; many of them were also on tractors.

A member of the Sankyukt Kisan Morcha, an umbrella body of 41 unions, leading the protest against the three Central farm laws at several border points of Delhi, said those who broke the barricades belonged to the Kisan Mazdoor Sangharsh Committee.

Eventually, the protesters entered Delhi even before the decided time.  

The protesting unions have also announced a foot march to Parliament on February 1, when the annual Budget is presented, to press for their demands including a repeal of the three new agriculture laws.

Heavy security has been deployed in view of the 'Kisan Gantantra Parade' that will move into Delhi from the Singhu, Tikri and Ghazipur border points.
