Zürcher Nachrichten - Hundreds of thousands defy Erdogan to protest Istanbul mayor's arrest

It was the third straight night that demonstrators had rallied against the arrest of Imamoglu -- Erdogan's biggest political rival -- in Turkey's biggest street protests in more than a decade.

Opposition leader Ozgur Ozel, head of the CHP which called the nationwide protests, told a vast crowd in front of Istanbul City Hall that "300,000 people" had joined the demonstration.

"This is not a CHP rally, the people here are from all parties and have come to show solidarity with Mayor Imamoglu and stand up for democracy," he told the vast gathering which punctuated his speech with cheering and applause.

Erdogan is "trying to twist Imamoglu's arm by using the judiciary as a weapon and take over this building. But we won't hand it over to a government-appointed trustee!" he yelled.

As he spoke, clashes erupted on the sidelines of the protest, with riot police firing tear gas and rubber bullets, according to two AFP correspondents who were both hit in the leg.

Clashes also broke out in Ankara and the western coastal city of Izmir where police fired water cannons and tear gas against protesters, an AFP correspondent and the opposition Halk TV said.

"Don't stay silent or it will be you next," chanted the demonstrators in Istanbul as the massive gathered at sunset with protesters waved placards reading: "Don't be afraid, the people are here!" and "Law, rights, justice".

"We did not take to streets by force. We are here because of Erdogan," 56-year-old Necla, who was wearing a headscarf, told AFP.

"I don't believe in the allegations about Imamoglu. There is no man as honest as him," she said.

- Street protests a 'dead end' -

The arrest came just days before Imamoglu was to have been formally named as the CHP's candidate in the 2028 presidential race.

The protests spread quickly from Istanbul to at least 40 of Turkey's 81 provinces, according to an AFP count.

As the CHP's Ozel urged people across the country to stand up, Erodogan said: "Turkey will not surrender to street terror.

"Let me say it loud and clear: the street protests that the CHP leader has called for are a dead end," he added.

He accused the opposition leader of "grave irresponsibility", raising concern that he too could face legal sanction.

On Friday, the authorities extended a protest ban to Ankara and Izmir. Ahead of the Istanbul rally, they blocked off the main access routes to City Hall, including Galata Bridge and Ataturk Bridge.

On Thursday, police fired rubber bullets and teargas at protesters in Istanbul and Ankara, where at least 88 protesters were arrested, Turkish media said.

Interior Minister Ali Yerlikaya said 16 police officers had been hurt. Police detained 54 people for online posts authorities deemed "incitement to hatred".

Prosecutors say they are investigating Imamoglu for "aiding a terrorist organisation" -- the banned Kurdish PKK militant group. They say they are also investigating him and around 100 other suspects for corruption.

- Currency, stock market, hit -

The move against Imamoglu has dealt a heavy blow to the Turkish lira, and on Friday the BIST 100 stock exchange was trading lower, shedding nearly eight percent just before 1400 GMT.

Despite Imamoglu's detention, the CHP has vowed it would press ahead with its primary on Sunday at which it would formally nominate him as its candidate for the 2028 race.

The party said it would open the process to anyone who wanted to vote, not just party members, saying: "Come to the ballot box and say 'no' to the coup attempt!"

Observers said the government could seek to block the primary to prevent a further show of support for Imamgolu.

"If a large number of people show up and vote for Imamoglu, it will further legitimise him domestically and really move things in a direction that Erdogan doesn't want," Gonul Tol at the Washington-based Middle East Institute, told AFP.
