Three Trinamool Congress workers have been killed in an intra-party clash at Onari village in Burdwan district on Sunday night.

Superintendent of police Kunal Agarwal said the three TMC workers were killed in a clash involving rival factions of TMC Block President Alok Manjhi and former block president Manir in Khandoghosh area of the district.

Trouble had been brewing between the two factions over area domination for quite some time and on Sunday the three workers, owing allegiance to Alok Manjhi, were attacked with lathis and rods, he said.

They were declared ‘brought dead’ at Burdwan Medical College and Hospital.

Six people were detained in this connection, the SP said.
