Speaking at an Ankara news conference, Nationalist Movement Party (MHP) leader Devlet Bahceli said Turkey should oppose the referendum which would include Turkmen-populated areas.
“This referendum, for Turkey, could be regarded as a reason for war, if need be,” Bahceli said.
On Sept. 25, Iraq's Kurdish Regional Government will hold a referendum on whether to declare formal independence from the Iraqi state.
Baghdad rejects the poll, saying it could adversely affect the ongoing fight against Daesh, which despite a string of recent defeats still maintains a significant presence in Iraq.
