Also on October 23, IS militants launched an attack on a town in Iraq's western Anbar Province in an attempt to divert attention from the offensive on Mosul, the last major IS stronghold in the country.
Kurdish Peshmerga forces launched fresh attacks to the northeast of Mosul, claiming to have recaptured the town of Bashiqa near Mosul from IS fighters.
Masud Barzani, president of the Iraq's semi-autonomous Kurdish region, told U.S. Defense Secretary Ash Carter that the Kurds had succeeded in liberating Bashiqa.
The capture of Bashiqa, if confirmed, would mark the removal of one more obstacle on the road to Mosul.
Reuters video footage from Nawran, a town near Bashiqa, showed Kurdish fighters using a heavy mortar, a machine gun, and small arms as smoke rose over the area.
"The Peshmerga have mobilized to cleanse the Bashiqa region from Daesh [IS]. They asked for help from our soldiers at the Bashiqa base. So we are helping the tanks with our artillery there," CNN Turk quoted Yildirim as saying.
Bashiqa is close to a military base with the same name where at least 500 and as many as 1,000 Turkish soldiers are training Sunni and Kurdish fighters for the Mosul offensive.
Posted there at the invitation of Iraq's northern Kurdish autonomous region, the Turkish forces have been training Sunni Muslim tribal fighters and Iraqi Kurdish Peshmerga troops in Bashiqa since late 2015, when the town was recaptured from IS.
Ankara's latest involvement in northern Iraq could further increase tensions with Baghdad, which has rejected an offer from Turkey to take part in the Mosul offensive.
