The Haryana Police on Tuesday hurled tear gas shells when a group of youth, who were part of the farmers' 'Chalo Delhi' protest march, tried to break barricades set up at the Shambhu border in Ambala.

Despite an appeal by the Haryana Police to stay away from the barricades, many youth continued to stay put and stood over the barricades, officials said.

When a few youth broke an iron barricade and tried to throw it off the Ghaggar river bridge, the police lobbed several rounds of tear gas shells.

They also used a drone later on to drop a teargas shell.

Farmers on Tuesday morning commenced their 'Delhi Chalo' march to press for their demands, after a meeting with two Union ministers over their demands, including legal guarantee to MSP for crops, remained inconclusive.

The Samyukta Kisan Morcha (Non-Political) and the Kisan Mazdoor Morcha have announced that farmers will head to Delhi to press the Centre to accept their demands, including the enactment of a law to guarantee a Minimum Support Price (MSP) for crops.
