Four Shatabdi trains have been cancelled while 35 other passenger trains were detained as protesting farmers squatted on railway tracks at 44 locations across Punjab and Haryana on Friday amid Bharat Bandh called by Samyukta Kisan Morcha against three farm laws.

Movement of 40 goods trains have also been affected by the protest.

The 44 locations where train movement has been disrupted fall under the Delhi, Ambala and Ferozepur divisions of the railways.

"As of 11 am, kisan agitators are sitting at 44 locations. Total 35 passenger trains have been detained and 40 goods trains are affected so far. Four Shatabdi trains have been cancelled," Northern Railways spokesperson Deepak Kumar said while quoted by PTI.

The Samkyukta Kisan Morcha (SKM) has called for the bandh from 6 am to 6 pm to mark four months of the farmers" agitation at Delhi"s three borders — Singhu, Ghazipur and Tikri.

Thousands of farmers, mainly from Punjab, Haryana, and western Uttar Pradesh, have been camping at Singhu, Tikri and Ghazipur borders demanding a complete repeal of the three farm laws and a legal guarantee for minimum support price on their crops.
