Days after barbed wire fences, concrete barricades and makeshift barriers of buses were put in place at Ghazipur on the Delhi-Uttar Pradesh border - to virtually imprison farmers protesting the agriculture laws - similar measures are being rolled out at Singhu on the Delhi-Haryana border. Delhi Police are digging up vast stretches of NH-44 to build rows of barbed wires set in concrete, and are setting up strips of sharpened nails and iron rods in the middle of the road - those pieces that have not been dug up - to stop farmers and their tractors from entering the national capital.
