"Nirbhaya case shook the conscience of the nation. Final verdict reminds all of us about our duty towards ensuring women safety (sic)," he tweeted.
The apex court today confirmed the death sentence awarded to the four convicts in the case, saying it had sent a "tsunami of shock" and was a "rarest of rare" case, in which the most brutal, barbaric and diabolical attack was carried out on the 23-year-old woman.
Those sentenced to death are Mukesh (29), Pawan (22), Vinay Sharma (23) and Akshay Kumar Singh (31).
