Uttar Pradesh Chief Minister Yogi Adityanath on Wednesday took part in ‘Jana Raksha Yatra’ in Kerala’s Kannur over the killing of Bhartiya Janata Party and Rashtriya Swayamsevak Sangh’s workers in the state. "This yatra is a mirror for communist governments in Kerala, WB and Tripura. They should put an end to political killings. There is no place for violence in a democracy, but political killings are continuing here," said Adityanath.
