A TMC delegation was detained at the airport here on Saturday when it was going to meet families of the Sonbhadra clash victims, party MP Derek O'Brien said.
After being denied permission to proceed, the delegation sat on a dharna at the airport here.
Ten people were gunned down and 28 injured in the clash between supporters of a village head and Gond tribals this week over a land dispute.
The Trinamool Congress (TMC) team of MPs comprises O'Brien, leader of the delegation, along with Sunil Mondal and Abir Ranjan Biswas.
In a tweet, O'Brien said: "After meeting families of those injured, Trinamool delegation stopped from proceeding to #SonbhadraMassacre spot. We shall continue our dharna at Varanasi airport."
Speaking after meeting the family members of the injured here, O'Brien said, "The team met the injured persons in the BHU Trauma centre. The UP Administration has not given us permission to go to Sonebhadra."
Soon after they were stopped from proceeding, O'Brien tweeted: "Trinamool Parliamentary delegation detained at Varanasi airport. ADM,SP have not told us under which section.(Doing as told from topmost).We have told them that we will cooperate,wish to meet injured & then proceed to Sonbhadra to meet & give confidence to grieving families (sic)."
