Accusing Maoist leader Kishenji of failing to address the grievances of the tribals, his long term aide Gurucharan Kisku has formed his own squad.

He said Kishenji is an "outsider" who did not understand tribal sentiments.

"Tribals have distinct customs, religion and language and the party is destroying the tribal way of life in Jungle Mahal and other areas," Kisku alias Marshal, who has been a squad member of the Maoist Communist Centre since 1988, told PTI in a telephonic interview.

Claiming that Maoists have failed to address the grievances of tribals, he said, "I decided to quit when I realised that the party was doing nothing for tribals and instead using them.

"The movement in Bengal is not a tribal movement as claimed by Kishenji, it is anti-tribal," Kisku said from an undisclosed location on the Bengal-Jharkhand border.
