Istanbul, AP—Prime Minister Recep Tayyip Erdoğan prepared to convene his party leadership Saturday as anti-government protests enter their ninth day, with thousands of people still occupying Istanbul’s central Taksim Square.

Erdoğan, who has said the protests must end immediately, was to meet with top officials from his Justice and Development Party in Istanbul.

The protests began as a sit-in at a park in Taksim Square to prevent a redevelopment project that would replace the park with replica Ottoman barracks and a shopping mall. The mall idea seems to have fallen by the wayside, with Erdoğan recently saying an opera house, theater and possibly a museum would be built instead.

But violent intervention by police to eject the protesters on May 31 outraged many, and the protests spread to dozens of cities across Turkey.

Over the past nine days of demonstrations and frequent violent confrontations with police, three people have been killed—two protesters and a policeman—and thousands have been injured.

The protests have attracted a broad array of people angered by what they say are Erdoğan’s increasingly autocratic ways and his intervention in private life. They point to attempts to curtail the selling and promotion of alcohol, his comments on how women should dress and statements that each woman should have at least three children.

A devout Muslim who says he is committed to upholding Turkey’s secular tradition, Erdoğan vehemently rejects charges of autocracy and points out that he enjoyed 50 percent support in the last elections in 2011.

Over the past week, protesters—mainly young, secular and middle-class, but also including some religious Muslims who were formerly Erdoğan supporters—have set up camp in Taksim Square and its Gezi Park. They have vowed to remain there until the development project for the area is canceled—something Erdoğan has shown no signs of being willing to do.

While Taksim Square has been generally quiet for the past few days, clashes have broken out in other parts of the city. Riot police used water cannons and tear gas against protesters who set up street barricades in the Sultangazi neighborhood on the outskirts of Istanbul overnight.

Witnesses said at least one person was injured, hit in the face by a tear gas canister. Early Saturday, blood stains could be seen on the ground amid debris from burned garbage bins and damaged shops.
