Thousands of Turks were expected to ramp up protests on Thursday over what they called the undemocratic detention of Istanbul's mayor Ekrem Imamoglu despite a ban on gatherings, police barricades and dozens of detentions over social media posts.

Police arrested dozens of people, including Istanbul Mayor Ekrem Imamoglu, who was expected to be the opposition party’s presidential candidate.
