Congress leader Sam Pitroda's remarks on the 1984 anti-Sikh riots were "absolutely and completely out of line" and he should apologise for them, party chief Rahul Gandhi said in a Facebook post on Friday.

"What Mr Sam Pitroda has said is absolutely and completely out of line and is not appreciated. I will be communicating this to him directly. He must apologise for his comment," he said, describing the riots — which claimed nearly 3,000 lives — as a "terrible tragedy", reports NDTV.
