Riot police fire tear gas at Istanbul crowds protesting mayor's arrest

Riot police in Istanbul fire tear gas, rubber bullets and pepper spray at crowds out protesting the arrest of the Turkish city's mayor, Ekrem Imamoglu, for the fourth night in a row.

His arrest took place days before a primary vote by the opposition CHP party to elect a candidate for the 2028 presidential election as the government accused him of "corruption" and "terrorism".

While one of his lawyers says a court has now formally placed him under arrest in a graft investigation, they have decided against doing so in a separate "terror probe".
