A doctored video splicing footage of President Tayyip Erdogan's main rival and a Kurdish militant chief and showing them uttering the same slogan has raised tensions ahead of a vote on Sunday marred by accusations of smear campaigns.
Opinion polls show Kemal Kilicdaroglu ahead of Erdogan. In a move seen boosting the president's rival, another of the four candidates withdrew from the race on Thursday, saying he was the target of election smears.
In his campaign, Erdogan has repeatedly suggested links between the outlawed Kurdistan Workers Party (PKK) and the opposition alliance, without providing evidence, tapping into nationalist hostility towards the PKK.
