"The (upcoming) process will show what will happen, but we will not give up. We won't be afraid. We won't be silent. They can do whatever they want. They can attack as much as they want. They can steal as much as they want. We will stand in front of them, sometimes with posters, sometimes as a whole group and sometimes struggling as individuals. This is how I see it."

"They can try to make people give up (fighting) with their approach. They've tried this before. But people are at the point where they're tearing down that wall of fear and whatever happens, people won't give up on showing their stance, standing behind their decision."
Hundreds of protesters took to the strees on Saturday to protest Turkey's top electoral authority's decision to cancel the results of a March 31 mayoral race for Istanbul, which was won by the opposition.
It ordered a revote for June 23.
The country's electoral board ruled in favour of a challenge made by President Recep Tayyip Erdogan's party, finding the poll on March 31 was invalid.
Ekrem Imamoglu of the opposition Republican People's Party, or CHP, had won the election by a slim margin, defeating the AKP ruling party's candidate, former Prime Minister Binali Yildirim.
Opposition protesters said that the decision to overturn the vote increases concerns over democracy in Turkey and raises questions over the ruling party willingness to accept electoral defeat and relinquish power.
Erdogan's party says the Istanbul vote was marred by fraud but the opposition says the electoral board was pressured by the government, which desperately wants to hold on to power in Turkey's largest city.
