Union Home Minister Rajnath Singh said the killing was an "act of cowardice" and described the Rising Kashmir editor as a courageous and fearless journalist. "He will be missed", he said on Twitter.
National General Secretary of Bharatiya Janata Party Ram Madhav said, "Shocked to hear about d attack on d Editor-in-Chief of Rising Kashmir Shujaat Bukhari in Srinagar".
Veteran journalist and editor of local newspaper Rising Kashmir Shujaat Bukhari and his two personal security officers (PSOs) were gunned down by militants at Press colony in Srinagar on Thursday.
Senior journalist Shujaat Bukhari has been shot dead by three bike-borne terrorists outside his office in Srinagar. "Justice will be done", Mehbooba said.
RJD leader and former deputy chief minister of Bihar Tejashwi Yadav wrote "shocked & saddened by the unfortunate news of @bukharishujaat 's death".
TV visuals showed her in tears as she recalled her meeting with the journalist just a few days ago. "Where we are heading as a country?" Long time associate, over 20 years. Regret to learn that he is no more. I strongly condemn this act of mindless violence and pray for his soul to rest in peace. Bukhari was shot in the head multiple times while he sat in a auto and a personal security officer (PSO), who was accompanying him, was also shot dead. His security guard died in the hospital, while another is in critical condition.
Bukhari, who earlier worked as The Hindu's Kashmir correspondent, was instrumental in organising several conferences for peace in the Valley. He was also part of the Track II process with Pakistan.
The 49-page report - the first ever issued by the United Nations on the human rights situation in Indian-Administered and Pakistan-Administered Kashmir - details human rights violations and abuses on both sides of the Line of Control, and highlights a situation of chronic impunity for violations committed by security forces.
