Farmers on Tuesday morning commenced their 'Delhi Chalo' march from Punjab to press for their demands, amid heavy barricading at Haryana-Punjab border and entry points into the national capital.
The Haryana Police 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, officials said.
