Turkey's prime minister has issued what he calls a final warning to anti-government protestors, demanding they leave a square in Istanbul. He also urged them to leave an adjoining park.
The demonstrators remain defiant, raising fears of a fresh clash with police.
The unrest started spreading across Turkey late last month with protestors battling police.
Prime Minister Recep Tayyip Erdogan delivered a speech in the capital Ankara on Thursday. He said the government is at the end of its patience.
Despite his ultimatum, thousands of demonstrators remained in the square and the adjoining park through the night.
Representatives of the protestors say they will meet the prime minister in Ankara on Thursday night to avert another violent clash. But it remains to be seen whether the talks offer any breakthrough.
