Istanbul Mayor Ekrem Imamoglu has appeared before police for questioning on terror-related charges a day after his interrogation over corruption allegations

Protests against the detention of Istanbul's mayor grew on Friday and turned increasingly tense, Turkey's biggest show of civil disobedience in more than a decade after President Tayyip Erdogan warned it would not be tolerated.

Despite Erdogan’s stern warning that street demonstrations would not be tolerated, unrest spread throughout the country, leading to violent clashes with police.
