ISTANBUL — Riot police fired water cannons and tear gas as they drove protesters out of Istanbul's Taksim Square and neighboring Gezi Park on Saturday, an intervention that came shortly after the prime minister warned that security forces "know how to clear" the area.
Within a half-hour, the sweep by white-helmeted riot police had emptied the park, leaving a series of colorful, abandoned tents behind. Bulldozers moved in afterward, scooping up debris as crews of workmen in hard hats and fluorescent yellow vests tore down the tents. Protesters put up little physical resistance, even as plain-clothes police shoved many of them to drive them from the park.
Erdogan warned protesters to cheers from the crowd: "I say this very clearly: either Taksim Square is cleared, or if it isn't cleared then the security forces of this country will know how to clear it."
The protests that were sparked after the violence police action on May 31 sparked a much broader expression of discontent about Erdogan's government, and what many say is his increasingly authoritarian decision-making.
The anger has been fanned because riot police have at times used tear gas, water cannons and rubber bullets to disperse mostly peaceful protesters. Five people, including a police officer, have died and thousands of people have been injured, denting Erdogan's international reputation.
Erdogan, who was elected with 50 percent of the vote for his third term in 2011, vehemently rejects the accusations by protesters and points to his strong support base.
A second pro-government rally is planned for Sunday in Istanbul, though Erdogan has previously said that the rallies were not designed as "an alternative" to the demonstrations at Gezi Park, but part of early campaigning for local elections next March.
On Saturday, Erdogan lashed out at what he called the "plot" behind the biggest street protests in his 10-year tenure.
"Over the last 17 days, I know that in all corners of Turkey, millions and billions have prayed for us," Erdogan said, as he moved about the stage.
"You saw the plot that was being carried out, the trap being set." He said his supporters represented the "silent masses."
"You are here, and you are spoiling the treacherous plot, the treacherous attack!" he said, insisting unspecified groups both inside and outside Turkey had conspired to mount the protests centered on Istanbul — and that he had the documents to prove it.
The crowd chanted in response: "Stand straight, don't bow, the people are with you!"
In his speech, he focused on some protesters who have clashed with polices — at time by throwing stones and firebombs.
"There is no breaking and burning here, we are people of love," Erdogan said. "If people want to see the real Turkey, they should come here to Sincan."
Erdogan already has offered to defer to a court ruling on the legality of the government's contested park redevelopment plan, and floated the possibility of a referendum on it. But concessions over the park seemed not to be enough,
