The protesting farer unions will observe 'Sadbhavna Diwas' on Mahatma Gandhi's death anniversary today and hold a day-long fast. They have also claimed that the farmers' proest will gain momentum and strength as more farmers join them in the coming days. The claim came as more farmer outfits have started mobilising more batches of farmers from Haryana and Punjab to head towards Delhi's borders to join the ongoing agitation against the farm laws as the government ordered to clear the sites of protest following the Republic Day violence.
