KANNUR (KERALA): The BJP has called for a strike in Kannur district of Kerala after a party activist was hacked to death. Sources said the attack of C Biju, 32, was led by a group of unidentified people. Security in the area has been tightened to avoid any further escalation. Kerala BJP chief Kummanam Rajasekharan said that Kannur should be declared a “disturbed area”. He added, “Since the government has failed to curb violence, AFSPA (Armed Forces Act) should be imposed there to maintain law-and-order.” He also alleged, “CPI(M) workers are unleashing violence against their political rivals and even the chief minister has failed to control them.”
