Celebrities not only condemned Lankesh's murder, but also the unsolved murder of three other outspoken critics of right-wing extremist ideology -- M.M. Kalburgi, Govind Pansare and Narendra Dabholkar.
Here's what they have tweeted:
Shabana Azmi: Gauri Lankesh shot dead outside her home. Shocking, devastating. Dabholkar, Pansare (and) Kalburgi culprits must be punished.
Javed Akhtar: Dhabolkar, Pansare, Kalburgi and now Gauri Lankesh. If one kind of people are getting killed which kind of people are the killers.
Shekhar Kapur: To kill someone for their views is not democracy, its beginnings of a Banana Republic, where violence speaks louder than words. Gauri Lankesh.
Renuka Shahane: Another liberal, rational voice snuffed out by 'unidentified assailants'. Gauri Lankesh RIP. Dabholkar, Kalburgi, Pansare. Who killed them?
Farhan Akhtar: Shameful. What kind of society are we becoming? Deepest condolences to the family and hope justice is delivered soon.
Shirish Kunder: When "intellectual" becomes an abuse, words are replied with bullets.
RIP. Gauri Lankesh.
Ashoke Pandit: First it was Hemant Yadav, Sanjay Pathak, Brajesh Kumar & Rajdeo Rajan & now #Gaurilankesh. Sad #RIP. #SiddhaRammaiya should resign.
Dia Mirza: This is deeply disturbing. Culprits must be found and punished. Gauri Lankesh.
Anubhav Sinha: How weak your argument must be when you have to kill a woman. #GauriLankesh
Saiyami Kher: Lord Ganesh bids us goodbye, watching the death of a gutsy journalist. He must be so glad he's leaving. Gauri Lankesh.
Nandita Das:
