"Along with West Bengal, three other states and one Union territory, went to the poll, but nowhere apart from this state, post-poll violence has been reported," Left Front chairman Biman Bose said.
Besides the protest march in the national capital, rallies would be held in the districts in the state where party offices were being targeted, Bose said, adding in some cases, houses of their supporters had also been burnt down.
He alleged that activists of the Trinamool Congress were spreading "terror" against the opposition in Kolkata and in the districts.
