ANKARA, Turkey -- Turkey's opposition party leader accused the prime minister of escalating tensions and dragging the country "into the fire" as enduring anti-government protests that have led to three deaths entered their 11th day on Monday.
Prime Minister Recep Tayyip Erdogan headed a Cabinet meeting to discuss the protests, the first serious challenge to his 10-year rule. On Sunday he had made a series of fiery speeches in three cities, saying the government's patience is running thin, demanding an end to the protests and threatening to hold those who don't respect his government to account. He didn't specify what that would entail.
Erdogan has also called major pro-government rallies in Ankara and Istanbul next weekend, apparently aiming to intimidate the protesters by showing that he, too, can get large numbers of his supporters out on the street.
Hurriyet newspaper on Monday quoted Kemal Kilicdaroglu, the head of the opposition Republican People's Party, as calling on Erdogan to reduce tensions.
"Why is the prime minister being so stubborn toward his people? He should not do it," Kilicdaroglu said. "We are witnessing a prime minister who is trying to hold on to power by creating tensions."
"A policy that feeds on tension will drag society into the fire," he added.
Crowds of protesters swelled into the tens of thousands in Istanbul's Taksim Square and main city centers in Ankara and Izmir as Erdogan delivered his speeches. Police broke up the protest near government buildings in Ankara with tear gas and water cannons.
The Turkish Human Rights Foundation said at least 12 people were detained in Ankara. It added that 13 were detained in the city of Adana for allegedly "inciting people into rioting" through social media posts. They were questioned by a court, which then released them from custody, the state-run Anadolu Agency reported. A further 25 protesters were detained in Izmir for a series of Twitter posts last week. They were also later released.
The protests were sparked May 31 by a violent police crackdown on a sit-in at a park in Taksim Square to prevent a redevelopment project that would replace the green space with a replica Ottoman Barracks. They have since spread to 78 cities across the country.
Protesters vent their anger at what they say are Erdogan's growing autocratic ways and his attempts to impose a religious and conservative lifestyle.
Erdogan, a devout Muslim, says he is committed to Turkey's secular laws and denies charges of autocracy.
On Sunday he denied he is raising tensions and insisted the protests are a ploy to undermine a government that was elected with 50 percent support in 2011 elections.
Protesters on Monday continued to occupy the park in Taksim Square, where dozens of tents have been set up.
"I am here because I don't want (Erdogan) and his government anymore, said 26-year-old Melisa Colakoglu. "Because it is not democratic."
Police in Ankara again removed tents from a small park where protesters have gathered in a show of support to the Istanbul protesters.
The Human Rights Foundation said some 4,850 people have sought medical care since the protests began, for injuries or the effects of tear gas. Two protesters have died, as well as a police officer who fell into an underpass while chasing protesters.
