Turkish news reports say police is carrying out raids and detaining people suspected of involvement in violence against police during a wave of anti-government protests.

NTV television says the raids in Ankara and Istanbul are targeting left-wing groups, which authorities suspect were involved in violent clashes with police.

Turkey's state-run Anadolu Agency said at least 25 people were detained in Ankara and many others in Istanbul.

Earlier, police detained a dozen people who stood still at Istanbul's Taksim Square in a form of passive defiance against Prime Minister Recep Tayyip Erdogan's authority after activists were ousted from a sit-in at a park over the weekend.

A wave of anti-government protest swept through Turkey starting May 31 that have shaken the country's secular democracy.
