The ruling BJP, often blamed by the opposition for a spike of mob killings in the country, hit back at the Congress, calling the 1984 anti-Sikh riots after former prime minister Indira Gandhi's assassination the country's "single biggest incident of mob lynching". Home Minister Rajnath Singh, who was speaking on the opposition-backed no-trust motion against the NDA government, said mob killings should be stopped. "But I want to say that the single biggest incident of mob lynching took place in 1984," he said.
