Congress demanded a judicial inquiry saying "grave allegations have been made but BSP dismissed the charges as "baseless".
Gandhi, who led an eight-member delegation to Singh, alleged later that huge heaps of ash carrying burnt bodies have been found in the villages where farmers were agitating for better compensation for their land acquired by Mayawati government.
Gandhi also showed the Prime Minister pictures purportedly of bodies burnt and other forms of violence against farmers and their family members.
"The issue here is a more fundamental one with regard to these villages in particular and a large number of villages in UP all down the Agra highway, where state repression is being used, where people are being murdered.
"Quite severe atrocities taking place there....There is a set of large 74 heaps of ash there with dead bodies inside. Everybody in the village knows it. We can give you pictures. Women have been raped, people have been thrashed. Houses have been destroyed," Gandhi told reporters.
