At least 150 Peshmerga fighters are heading towards Turkey from where they would cross into Syria to fight Islamic State (IS) militants besieging the town of Kobane.
According to the BBC, around half of the fighters are going by air while the other half is travelling by road carrying heavy weapons.
Turkey agreed to the operation last week after refusing to allow Turkish Kurds to cross the border area to fight.
Turkish Prime Minister Ahmet Davutoglu had earlier rejected claims that he was not doing enough to end the jihadists' assault.
Davutoglu said that there's need for a military operation to save and retake Kobane and areas around the town.
