Disinformation adds dark note to pivotal Turkish election
The clip lasted 14 seconds, presented by Turkish President Recep Tayyip Erdogan as proof that his rival in Sunday's election was running "hand in hand" with outlawed Kurdish militants.
Aired at a huge rally and beamed live on TV, the video showed opposition leader Kemal Kilicdaroglu trying to rally his supporters to the tune of his campaign song.
In the next sequence, members of Turkey's banned PKK group echoed that call while clapping their hands to the beat of Kilicdaroglu's election jingle.
