Turkey authorities detained 343 people during Friday night's protests in several cities over the arrest of Istanbul's mayor Ekrem Imamoglu, announced the Ministry of Internal Affairs of Turkey.
Demonstrations were held in more than ten cities, including the largest city Istanbul and the capital Ankara, and the Ministry pointed out that people were detained to prevent disruption of public order, but also as a warning that the government will not tolerate chaos and provocations.
Tens of thousands of Turkish citizens have taken to the streets in mostly peaceful demonstrations since Wednesday, when Imamoglu was detained on charges of corruption and aiding a terrorist group.
He is the main political rival of Turkish President Recep Tayyip Erdogan, and has a better rating than him in some public opinion polls, writes Reuters.
Authorities in Ankara and Izmir imposed a five-day ban on demonstrations on Friday, following a similar ban earlier in Istanbul. Nevertheless, Ozgur Ozel, the president of the opposition Republican People's Party (CHP), issued a new call to people to gather and demonstrate.
"To those who say that calling people to the streets is irresponsible, I say: we are not the ones who fill these streets and squares. Your lawlessness and injustices brought people to the streets," Ozel said.
Imamoglu's arrest came just days before he was expected to be nominated as the presidential candidate of the CHP, the main opposition party, in Sunday's primary.
Ozel said the primaries, in which about 1,5 million delegates can vote, will go ahead as planned.
Analysts say Imamoglu could be replaced if he is formally charged with links to the outlawed Kurdistan Workers' Party (PKK), which Turkey and its Western allies treat as a terrorist organization.
