NEW DELHI: There can be no "formal" talks with the government until "harassment" by police and administration stops and detained farmers are released, the Samyukt Kisan Morcha said on Tuesday.

In a statement, it alleged that increased barricading, including digging trenches, fixing nails on roads, setting up barbed-wire fences, closing internal roads, stopping Internet services and "orchestrating protests through BJP-RSS workers" are part of "attacks" being organised by the government, its police and administration against the farmers.

The umbrella body of farmers' unions protesting the Central farm laws termed the "frequent Internet shutdown" at protest sites and blocking of many Twitter accounts related to the farmers movement "direct attack on democracy".

Twitter on Monday blocked several accounts and tweets after the government asked the microblogging platform to take action against 250 handles and posts for containing ''false and provocative content" related to the ongoing farmers' agitation, according to PTI sources.

"It appears the government is extremely fearful of the rising tide of support for the ongoing protest from different states," the Samyukt Kisan Morcha (SKM) said.

Farmers, mainly from Punjab, Haryana and Uttar Pradesh, are protesting the Centre's farm laws for more than two months at the borders of the national capital, choking highways to neighbouring states.

"The SKM decided in its meeting on Monday that there can be no formal talks with the government until police and administration''s harassment of different kinds against the farmers'' movement is immediately stopped," the SKM said.

It also said no formal proposal for talks has been received by it.

"Though no formal proposal for talks came from the government, we clearly state that the talks will be held only after the unconditional release of farmers who are in illegal police custody," the statement said.

Prime Minister Narendra Modi in an all-party meeting on Saturday had said the government''s offer to suspend the farm laws for 18 months was still on the table and the Agriculture minister Narendra Tomar was just a phone call away to take the talks forward.

The Morcha had reacted to PM Modi's statement by reiterating its demand for the repeal of the three agri laws.
