Lok Sabha saw opposition members storming into the Well of the House and resorting to noisy protests and sloganeering.
Led by deputy leader of Congress in Lok Sabha Gaurav Gogoi and Congress general secretary K C Venugopal, the opposition members also sought suspension of the Question Hour and demanded a discussion on the stampede.
Lok Sabha Speaker Om Birla said the Question Hour, where important issues are discussed, should not be disrupted and the opposition members should allow the House to run smoothly.
The House took up 18 questions with brief replies from ministers. Usually, 20 questions are listed for oral replies during the Question Hour every day.
Opposition members, including those from Congress, DMK, TMC and SP, returned after conclusion of the Question Hour, shortly after walking out.
