Muzaffarnagar: The Bharat Kisan Union (BKU) has demanded the arrest of those responsible for the violence in riot-hit Muzaffarnagar in Uttar Pradesh.
The death count from the violence has been pegged at 38 lives so far. Hundreds have been forced to flee their homes.
The BKU has also called for the rehabilitation of thousands of riot survivors.
Some reports said the violence broke out when a mob attacked a vehicle after the meeting.
Three of the politicians were from the Bharatiya Janata Party and one from the Congress party, which heads the national coalition government.
A sting operation had allegedly revealed the involvement of senior leaders and the Government of Uttar Pradesh in the violence that rocked Muzaffarnagar district of the state.
During the sting operation, the officials admitted that there was pressure from the top and they were forced to release the rioters.
Bharatiya Kisan Union leader Rakesh Tikait on Thursday called for strict action against perpetrators of violence.
"You cannot deny that there is political hand in the current situation. The people who are in the government, they should take action," said Tikait.
Police had evacuated Hindu and Muslim villagers on Monday in the district of Muzaffarnagar, 130 km northeast of New Delhi.
Some locals, fearful after the attackers beat children and burned property, hid in fields and police stations, or fled in ox carts and tractors on Sunday.
The chairperson for the National Commission on Minorities, Wajahat Habibullah, said that the area of concern was to ensure safety and security of the victims.
"The concern is related to the administration and the way we can help the administration so that people who have been rendered homeless are rehabilitated," said Habibullah.
