State CPI(M) secretary Ali Kishore Patnaik said the BJP members could not cause much damage to the CPI(M) office on Saturday due to timely intervention by police. He alleged that the attackers used filthy language against the Left party and "threatened to finish our members."
It is part of a conspiracy hatched by RSS to silence the people opposing its ideology and policies, he charged at the protest meeting.
BJP is trying to dislodge the CPI(M)-led Left government in Kerala, Patnaik alleged, adding that a CPI(M) cadre was killed in the southern state earlier this month.
A number of other Left leaders also addressed the meeting.
