A group of over 200 people threw stones and vandalised tents erected by farmers at the Delhi-Haryana border in Singhu, the epicenter of farmers' protests since over two months. A police official was injured with a sword in the violence. The sudden violence this afternoon at the protest site, which has been tense since the Republic Day violence, prompted the police to use tear gas shells and resort to lathi-charge. Farmers too appealed for calm.
