More than a dozen people have been detained over violence against an opposition election rally in Turkey amid growing concern over the fairness of Sunday’s knife-edge vote.

Istanbul mayor Ekrem Imamoglu of the main opposition Republican People's Party, CHP, was speaking on top of a campaign bus in Erzurum when about 200 protesters began throwing stones, forcing the event to be cut short.

He was campaigning on behalf of the CHP leader and presidential candidate Kemal Kilicdaroglu, the main opponent to President Recep Tayyip Erdogan.
