SHAMBHU, (India): Indian farmers demanding higher prices for their crops burned effigies of Prime Minister Narendra Modi and other ministers on Friday as they sought to expand their protest against his government months before elections.

Thousands of farmers began a ‘Delhi Chalo’ (Let’s go to Delhi) march last week but were stopped by security forces about 200 km (125 miles) north of the capital, with water cannons and teargas being used to push them back.

Farmer leaders on Thursday announced a series of “mega programmes” across India to press their demands. The “Black Day” on Friday will be followed by a tractor rally on highways on Feb. 26, and a farm workers’ public meeting in Delhi on March 14.

Black flags were hoisted on tractors and trolleys lined up at the protest site on Friday. Several protesters, most of whom are Sikhs from the northern state of Punjab, also tied black cloth over their turbans in solidarity.

Farmers also burnt effigies also of Home (interior) Minister Amit Shah and the chief minister of Haryana state, whose police force they accuse of using force against them, and chanted slogans demanding minimum prices for their crops.
