Thousands of farmers carrying sticks and swords flung police barricades into a river and threw bricks this morning as they tried to force their way into Haryana for a protest march in Delhi. Tear gas shells and water cannons were used to push back the farmers, who temporarily retreated but came back in larger numbers to clash with the police on a bridge just outside Haryana. Haryana, ruled by the BJP, has been using heavy force to try and block farmers making their way from Punjab towards Delhi in tractors and on foot for their two-day "Delhi Chalo" protest march against new farm laws that they fear will reduce their earnings and give more power to large retailers.
