In their 33rd Saturday's protest #1 in 5 million, the Belgraders accused President Aleksandar Vucic of dividing the people, telling him he would not succeed, the Beta news agency reported.
Branislav Lecic, an actor, said the authorities wanted "people to keep silent and yield to their lies since they have occupied the media."
That, according to him, would not happen. "This is an honest nation who fought for its freedom."
"We'll win because this malformed system created by Aleksandar Vucic and his collaborators can not survive," Lecic said.
Oliver Toskovic, a professor, said "Vucic is trying to divide the citizens" and that everything "he says is a manipulation."
"The rebellion is all we have since it shows they cannot do whatever they want," he said.
Not far from the Terazije square and #1 in 5 million protesters, the newly formed group of Belgrade intellectuals "Self-defence" gathered outside Serbia's Parliament and Presidency buildings to demonstrate against the verbal attacks on a journalist and a commissioner, the Beta news agency reported.
The group protested over the insults to Snezana Congradin, a journalist with the independent Danas daily and Brankica Jankovic, the Commissioner for Protecting Equality during the Parliament sessions.
The two were attacked by a convicted war criminal and the leader of the ultra-nationalist Serbian Radical Party (SRS) Vojislav Seselj. He offended Congradin because of her reportage from Srebrenica in which she wrote that what happened there was a genocide, as ruled by the two international courts.
Jankovic reacted, saying his words brutally violated the laws, prompting Seselj's new attack on her.
On Saturday, Dragoljub Bakic, an architect, told Beta the protest was organised "to confront the evil which wildly filled the atmosphere these days, hitting the heads of these two courageous women."
"This is our way to protect them," Bakic said. He added they "take photos outside the Parliament building and Presidency office because we believe the evil is generated under their roofs."
He said that Serbia's citizens were not malicious, and that "this evil lasts for 30 years," but that now it crossed all the lines."
