WATCH: Riot Police Crack Down on Reviving Protests Across Turkey

Protesters trying to rekindle the protest after the two-week protest was cleared from Gezi Park by the police on Saturday.

Turkish riot police with water cannons and tear gas on Sunday cracked down on protesters who remain defiant after authorities evicted activists from an Istanbul park.

The clampdown indicated authorities were taking a hardline against attempts to rekindle the protests. In Istanbul, police battled protesters in side streets off Gezi Park and beyond.

In Ankara, the capital, police dispersed hundreds who tried to hold a memorial service for an activist who died of injuries sustained in a nearby police crackdown nearby on June 1.

A police crackdown on peaceful campaigners in Gezi Park two weeks ago provoked an unprecedented wave of protest against Erdogan, drawing in secularists, nationalists, professionals, trade unionists and students who took to the streets in protest at what they see as his autocratic style.

The unrest, in which police fired teargas and water cannon at stone-throwing protesters night after night in cities including Istanbul and Ankara, left four people dead and about 5,000 injured, according to the Turkish Medical Association.

The protesters, who oppose government plans to build a replica Ottoman-era barracks on Gezi Park, had defied repeated calls to leave.
