Fighters with the Kurdistan Workers' Party, known by a Kurdish language initials PKK, began leaving Turkey Wednesday as a part of an ongoing peace process.
In a statement on its website, the Iraqi Foreign Ministry said the country "does not accept the entry of armed groups into its territory," claiming it would "undermine the security and stability" of Iraq and neighboring countries, Hurriyet Daily News reported Friday.
PKK spokesman Ahmet Deniz said Thursday the militants hadn't reached Iraq.
Around 200 militants are reported to have reached a PKK camp in Zap in northern Iraq.
New camps being created are said to be able to accommodate 1,500-2,000 militants.
