Turkish President Recep Tayyip Erdogan on Tuesday warned the Iraqi Kurdish leader against pushing for independence after holding a non-binding referendum, saying such a move risked sparking an "ethnic war" in the region.

"If (Massud) Barzani and the Kurdish Regional Government do not go back on this mistake as soon as possible, they will go down in history with the shame of having dragged the region into an ethnic and sectarian war," Erdogan said in a televised speech
