Turkish PM Recep Tayyip Erdogan says he will not step down amid corruption allegations that have forced the resignations of three ministers, the BBC reports.
The ministers’ sons were among dozens of people detained as part of a wide-ranging corruption probe.
Turkey’s army has said it does not want to get involved in political arguments, in response to rumours of a coup plot.
On Friday police fired tear gas and rubber bullets to break up protests in Istanbul’s Taksim Square.
Protests were also held in the capital Ankara and the third-largest city Izmir.
Protesters had chanted “catch the thief” and called for Mr Erdogan’s resignation.
Police are investigating allegations of illicit money transfers to Iran and bribery for construction projects.
The scandal has caused Turkey’s lira to fall to a new low against the dollar.
