All these riots were blots on the country for which all Indians were ashamed, Kumar said and asked those responsible for the carnage to own up responsibility.
"Nobody could escape accountability for these incidents," the chief minister told reporters in reply to a question on Congress Vice-President Rahul Gandhi's interview to a national news channel yesterday.
In the interview, Rahul Gandhi said the Narendra Modi government was responsible for "abetting and pushing" the 2002 Gujarat riots while the Congress government tried to stop the 1984 riots.
Kumar slammed the RJD-led government headed then by Lalu Prasad for closing the investigation in the Bhagalpur riots case after assuming power in 1990, despite the facts that there were material evidences available to bring the culprits to book.
It was his government that pursued the Bhagalpur riots case and brought the culprits to justice, besides providing assistance and relief to the victims and pension to the those displaced in the incident, Kumar said.
