Thousands of people have gathered outside Istanbul’s city hall for a second consecutive night to rally against the arrest of the city’s mayor.

The detention of Ekrem Imamoglu, a prominent contender against President Recep Tayyip Erdogan, was viewed by many as a politically driven attempt to eliminate a key rival from the next presidential race.
