New Delhi/IBNS: Protesting farmers, on a 'Dilli chalo' march Friday afternoon with a list of nearly five-year-old demands, including a legal guarantee for Minimum Support Prices (MSP), were forced to call a temporary halt after tear gas shells were fired by police blocking their path to the national capital.

Eight people were injured, and two others seriously wounded, according to farmers, during the clash that took place on National Highway 44, near Shambhu on the Punjab-Haryana border.

"Police used their full force against us. We were quite disciplined and were holding the protest peacefully. We knew we wouldn't be able to fight the might of the force used against us," farmer leader Sarwan Singh Pandher told reporters.

"So we have called back the protest for today," he said.

Police fired tear gas shells at farmers who were camping at the Shambhu border close to Haryana's Ambala when they tried to break barricades in their attempt to reach Delhi as a part of their protest on Friday.

According to reports, one of the protesting farmers has been detained by the police.

Farmers are protesting to seek a legal guarantee for MSP for crops.

Police had earlier stopped the farmers when they tried to march towards Delhi on February 13 and February 21.

Since then, these farmers have campaigned in Shambhu and Khanauri border points under the Samyukta Kisan Morcha (Non-Political) banner and the Kisan Mazdoor Morcha.

Tight security arrangements were tightened for the march.

The farmers, who were seen waving tri-colour, broke one layer of barricade that was placed to stop their further movement.

Meanwhile, internet service has been suspended till Ambala till December 9 by keeping the march in mind.

The Ambala administration has even banned the gathering of five or more people.

"We have been sitting here for the past eight months. In response to accusations that our tractors are modified, we have decided to march to Delhi on foot," farmer leader Sarwan Singh Pandher was quoted as saying by India Today.
