Her assassination came days after the second anniversary of the killing of Kannada writer and rationalist M M Kalburgi.
Activist-journalist Gauri Lankesh, who was gunned down outside her home in Bengaluru last month, will be posthumously given the Anna Politkovskaya Award this year, making her the first Indian to receive the honour, her family said on Thursday.
Lankesh will share the annual award, instituted in memory of a Russian investigative reporter who was assassinated last year in Moscow, with Pakistani activist Gulalai Ismail.
Ismail is fighting rightwing extremism in Pakistan.
The award is conferred by London-based organisation RAW in WAR (Reach All Women in War), and the announcement about Lankesh winning it was made to the media in Bengaluru by her mother Indira, brother Indrajit and sister Kavitha Lankesh.
"Today, we received an email from Russia that my sister has been chosen for the Anna Politkovskaya Award. She is the first Indian recipient of the award," Kavitha said.
"Anna was an activist-journalist just like my sister. She was killed on October 7, 2006, when she was in a lift. Five people accosted her and poisoned her," she said, quoting from the email.
She was killed for speaking up against the human rights violations in then-restive Chechnya province of Russia and exposing corruption.
"In her name, the award has been instituted exclusively for women, to honour those who work towards upholding the human dignity, especially of women and children," she said.
Indrajit said, "I have lost my sister. I appeal to the government to nab the murderers. Finding out the motive may solve the riddle of M M Kalburgi, Narendra Dabholkar and Govind Pansare murder (all rationalists) cases."
Whether he was satisfied with the investigation by the 21-member Special Investigation Team formed by the Karnataka government, he said they wait for the killers to be caught.
"We can't say we are happy with the investigation till the killers are found. But we are satisfied with the work they are doing," Kavitha said.
She expressed unhappiness over speculative stories appearing in the media.
Gauri Lankesh, the founder-editor of the 'Gauri Lankesh Patrike' and known to be an anti-establishment voice, was shot dead by unidentified men outside her residence on September 5.
On October 3 this year, Karnataka minister Ramalinga Reddy claimed the SIT has identified the killers. He, however, did not share the details, saying the SIT was gathering more evidence.
Her assassination came days after the second anniversary of the killing of Kannada writer and rationalist M M Kalburgi, who fell to bullets fired by two unidentified men at his residence at Dharwad in north Karnataka in August 2015.
