"They (Peshmerga) asked for help from our soldiers at Bashiqa base. We are providing support with artillery, tanks and howitzers," Yildirim told reporters in western Turkey.
At the base, Ankara says some 700 Turkish soldiers are training Iraqi fighters to help remove the Islamic State group from the country.
It has been a week since Iraqi forces and Kurdish Peshmerga supported by the US-led coalition began a major offensive to recapture Mosul, Iraq's second biggest city, from IS.
Tensions heightened after the Iraqi government referred to the Turkish soldiers as an "occupying force" in the first week of October and have continued to escalate. Abadi said yesterday that Baghdad did not need help from Turkey to liberate Mosul.
Yildirim said Tuesday that Turkish jets joined in the coalition's air operations during the long-awaited offensive. Erdogan has insisted that it is "out of the question" for Turkey not to be involved in the Mosul operation in some way.
