Turkish Prime Minister Recep Tayyip Erdogan has held talks with members of a key protest group, hours after issuing a "final warning" to demonstrators, BBC News reported.

Tayfun Kahraman from the umbrella group Taksim Solidarity described the outcome as "positive".

A meeting would be called in Istanbul's Taksim Square on Friday "to allow citizens to make up their own mind".

Taksim Solidarity is opposed to the redevelopment of Gezi Park, the issue that sparked the unrest.

Clashes between police and protesters in the park and nearby Taksim Square have continued for nearly two weeks.

Activists have said they will not leave until the government abandons plans to redevelop the park.
