Police clashed with protesters in Osmanbey and Sisli, northern districts of Istanbul, hours after Taksim Square and Gezi Park were cleared of demonstrators.
Police used teargas and water cannon to disperse the crowds.
Some residents showed support for the activists by banging pots outside their windows and beeping their car horns.
Thousands gathered for a peaceful protest in the capital Ankara; a show of support for the demonstrators in Istanbul and a stand against the government of Prime Minister Recep Tayyip Erdogan.
For more than two weeks, protesters in Istanbul’s Gezi Park defied Erdogan’s warnings that they must vacate but police evicted them on Saturday June 15.
