An RSS worker was hacked to death, allegedly by CPM workers at Nenmeni, Guruvayur on Sunday afternoon, the police said.
The victim, Anandan, 23, was riding a motorcycle when he was attacked by the CPM workers in a car. Though he was rushed to the hospital, his life could not be saved, police said.
Anandan, hailing from Brahmakulam, was an accused in a case relating to the murder of Fazil, a CPM worker, in 2013.
BJP has alleged that as many as 120 BJP workers, 84 in Kannur alone, have been killed in Kerala since 2001. It has claimed that 14 of these killings have taken place since Chief Minister Pinarayi Vijayan took over the reins of the government in May last year.
The CPM has in turn, accused BJP and RSS of resorting to violence and denied the involvement of its government and leadership in political killings.
There are unconfirmed reports that the BJP and RSS are likely to observe hartal in Thrissur district on Tuesday.
