KUALA LUMPUR, MALAYSIA: Youths should not take their frustrations to the streets, said Barisan Nasional Youth chairman Datuk Seri Hish-ammuddin Hussein.

"We cannot prevent youths from expressing themselves but they can do so in a controlled environment which we will monitor closely," he said after a rally at the Putra World Trade Centre to show youths' support for the monarchy.

Hishammuddin said the youths who had gathered here last night did not bring their frustrations to the streets by lying on the road as others had done in Kuala Kangsar, referring to Pakatan Rakyat supporters who had blocked the Raja Muda's car.

He condemned those who misused democracy to incite hatred and stir up the emotions of youths to act violently.

"The youths here tonight (last night) wanted to show their support for the monarchy and that they will protect the rulers because they are the backbone of this nation."

Earlier, Perak Menteri Besar Datuk Dr Zambry Abdul Kadir issued a warning to those who wished to bring down the monarchy and spread anti-monarchy sentiment.

"Stop doing so because it is enshrined in Rukun Negara that people must support the king and the monarchy.

"Those who are involved, be warned, we will take them on."

Present were BN deputy chairman Khairy Jamaluddin, MCA Youth deputy secretary Loh Chew June and MIC deputy Youth chief S. Murugesan.

More than 2,000 youths from political and non-governmental organisations had gathered to show their support to the royalty.

They chanted "Daulat Tuanku" as they walked into the hall. Several held flags and banners which stated their support for the king and sultans.

Most of them had a yellow strip of cloth with the words "Daulat Tuanku" around their heads, arms and songkok.
