After a large number of farmers from Punjab, who are heading for indefinite 'siege' of Delhi from November 26 over their demand to revoke the Central farm laws, were not allowed to enter Haryana owing to travel restrictions there, farmers' bodies on Tuesday threatened to block the highways. BharatiyaKisan Union (BKU) President Balbir Singh Rajewal said Haryana Chief Minister ManoharLalKhattar has sealed borders for Punjab farmers to prove that "Punjab is not part of India". "We will peacefully block the routes to Himachal and Jammu and Kashmir. Will start dharna on the roads," he tweeted. Rajewal questioned Khattar for refusing to give passage to the farmers to go to the national capital. "Can't the high court take suomoto notice to give justice to the peaceful farmers," he asked.
