Last month, Gandhi tried to reach Umbha village but was detained at the borders of Mirzapur district.
The Congress leader will also talk to the affected families about the development works in the Umbha village and try to get an account of the steps taken by the government for their security.
Sonbhadra firing: Yogi transfers District Magistrate, SP; axe falls on 8 gazetted, 7 non-gazetted officers
Even those who were involved in such land deals in Sonbhadra, Robertsganj and Mirzapur since 1955 would be brought to books if alive, the CM added.
All India Congress Committee secretary Bajirao Khade distributed cheques of Rs 10 lakh each to the next of kin of the deceased.
The Umbha firing is not an isolated case. Those familiar with Sonbhadra believe that if enough immediate steps are not taken in time, it will be difficult to stop such violence in the future too.
The Congress leader, who spent Friday night at a guesthouse in Mirzapur, said that the Sonbhadra victims had come on their own today to meet her but were detained by the police.
The Congress alleged that the BJP government wants to "deport" Priyanka Gandhi Vadra so that she cannot meet the victims of the Sonbhadra clash.
Congress leaders Deepender Singh Hooda, Mukul Wasnik, Raj Babbar, Ratanjit Pratap Narain Singh, Jitin Prasada and Rajeev Shukla were also stopped at Varanasi airport on Saturday by police.
Priyanka cannot politically afford to return to Delhi since that would reflect poorly on her party whereas if Yogi allows her, it will be a major victory for the Congress.

Outside Priyanka's room, police personnel maintained tight security vigil throughout the night while Congress workers slept on the floor, a little distance away.
Priyanka sat on a 'dharna' along with party workers when she was stopped by the cops in Mirzapur. She was subsequently picked up by the District Magistrate and taken to an unknown location.
