Rajya Sabha was adjourned till 12 p.m. on Thursday after Congress members created a ruckus in the House over Prime Minister Narendra Modi's remarks against Renuka Chowdhury's laughter.

On Wednesday, the Prime Minister took a dig at Congress member over her loud laughter at his claim that the idea of Aadhaar was conceptualised during the Atal Bihari Vajpayee government.

"Chairman Sir, don't stop Renukaji. Ever since seeing "Ramayana" serial, for the first time I have got an opportunity to see such a laughter," Modi had said, to a thumping of desks by the treasury benches.

On Thursday, soon after the Zero Hour began, Congress members rose from their seats and started shouting slogans.

Rajya Sabha Chairman Venkaiah Naidu asked the agitating members not to disturb proceedings of the House, but the Congress continued with their protests.

"It is totally unbecoming, undemocratic. Go back to your seats... You want the House to be adjourned?" he said and added: "I have no option other than to adjourn the house."

He then adjourned the House till noon.
