Chandigarh: The call for a 10- hour Bharat Bandh today by the Samyukt Kisan Morcha (SKM), (an umbrella body of over 40 farmer unions) against the three contentious farm laws started today at 6 am and will remain till 4 pm. As per reports, hundreds of farmers on Monday blocked major highways, including National Highway 1 linking Delhi with parts of Haryana and Punjab, following a nationwide call by farmers' unions to demand scrapping of three Central farm laws.Traffic across Punjab and Haryana is likely to hit badly and see traffic disruptions for several hours as farmers, farm labourers, commission agents, trade and employee unions and activists of political parties squatted on national highways till 4 p.m.The protesting farmers parked their tractors on highways and major link roads in both Punjab and Haryana and squatted on the road. Heavy police presence could be seen at various places in Haryana and Punjab to maintain law and others in view of the protest by farmers.The police diverted traffic at several places as the farmers blocked the highways. However, there was no report of any untoward incident from anywhere in the states. Emergency medical services were exempted from the blockade.The agitated farmers are demanding the repeal of the three farm laws passed by Parliament last year and have expressed apprehension that they would pave the way for the dismantling of the minimum support price system, leaving them at the mercy of big corporate houses.The government has maintained that the new laws will provide farmers with better opportunities. It has also accused the opposition parties of misleading farmers.
