Wrong message will go," he said.He said discussion on all issues including on Cauvery river issue will be allowed."We have paid tribute to nine persons who gave their lives to protect Parliament... I don't want these scenes to be seen," he said.As his repeated pleas to members to allow the House to function fell on deaf years, he adjourned the proceedings till tomorrow.Earlier, when the House met for the day, Naidu mentioned that Thursday was the 17th anniversary of the dastardly terrorist attack on Parliament.Condemning the incident, he said let us resolve to fight terrorism in all its forms."Let us remember the supreme sacrifice of brave hearts who laid down their lives to protect the temple of democracy," he said.Members stood in silence as a mark of respect to those killed in the attack.
