"Everyone felt some foul smell. We didn't know the cause, so the Speaker said it was better to adjourn the House for some minutes," said CPI leader D Raja.
The incident occurred at 11.30 am during the Question Hour when a Congress member pointed to a possible gas leakage. Soon other MPs too complained of foul smell.
The House was adjourned for 15 minutes following Chairman Hamid Ansari's instructions.
