BJP president Amit Shah on Tuesday launched a scathing attack on the ruling LDF in Kerala, saying Chief Minister Pinarayi Vijayan was responsible for the political murders of BJP and RSS workers in the state.

The BJP chief inaugurated the party's "jana raksha yatra" (march for people's protection) from Payyanur in Kannur. The march is expected to travel through the state before culminating in Thiruvananthapuram on October 17.

As part of the padayatra, Shah walked past the home of Chief Minister Vijayan, as a mark of protest against the ruling CPM's "political violence" and also against growing jihadi terrorism.

The veteran BJP leader said the march was a non-violent protest against the political killings. "We started the march from Kannur because it is the Chief Minister's home district."

Shah said as many as 120 BJP and RSS workers have been murdered in Kerala since 2001 and asked the CPM-led government to let the people know who was responsible for such killings.

"I am asking Chief Minister Vijayan who has killed BJP and RSS workers in Kerala. If he does not have answers, then I am saying CM Vijayan is responsible for it," he told a gathering in Kannur.

Shah said the attacks against RSS and BJP workers have spiked whenever CPM assumed power in the state. At least 84 of the 120 political murders occurred in Kannur - the Chief Minister's hometown, the BJP chief said.
