KUALA LUMPUR: Up to 20,000 red shirt supporters are gathering at an undisclosed location here Tuesday night.

Mohd Ali Baharom, president of the Army Veterans Association, said his team, comprising army veterans, would arrive Tuesday night at a "fifth checkpoint", which has yet to be announced.

"They will be located at an undisclosed venue," said Mohd Ali, who is popularly known as Ali Tinju.

He also said they were ready to confront any "provocation" during the Sept 16 rally.

"We don't want to hear what the police have to say, this is our right," he said.

Mohd Ali is no stranger to controversy, as he had been called in by the police over a speech he made following a brawl at Low Yat Plaza in July.

He was subsequently investigated under the Sedition Act.

He was also previously involved in a "butt dance" exercise which took place in front of former Bar Council chairman Datuk S. Ambiga's residence in 2013.

The rally, dubbed as "Perhimpunan Rakyat Bersatu", will be led by the National Silat Federation (Pesaka).

Their meeting points will be the Federal Territory Mosque, National Mosque, PWTC and Wisma Kratangan before converging at Padang Merbok.

However, red shirt supporters led by Sg Besar Umno division chief Datuk Jamal Yunus, insisted that the rally be called "Perhimpunan Pertahankan Maruah Melayu (Rally to Defend Malay Dignity)".

He said the rally was just a form of solidarity for Malays, which he claimed had been "continuously ridiculed" by the "Chinese DAP".

"We cannot stand all these insults. The rally will send a reminder to them that we need to respect each other," he told the press here, Tuesday.

He also assured that the rally would not incite racial hatred and would remain peaceful throughout the day.

"Any rumours suggesting that there would be a riot in order to create fear among the traders are false.

"We are good people," he said.

Jamal, however, believed that the recent Bersih 4 rally was racist.

"They were the ones promoting hatred towards the leaders and the Malays. We don't do all that," he said.

He also said they would provide 4,000 additional security members from 250 NGOs that he led to control the crowd.

"And 80,000 people will be coming from my side. They are not paid to come, all are coming voluntarily," he said.
