Despite continuing talks and Turkish lawmakers recently passing a motion enabling foreign forces to use its bases, Turkey's Prime Minister says no deal has been reached allowing the US to use the Incirlik air base.
The country is facing increasing criticism, as Ankara has been reluctant to get too aggressively involved in the war against Isis.
Turkish tank crews could be been seen lying idle across the border while Kobani was besieged.
So far, the country has agreed to lend its soil to 'moderate' Syrian rebels to be trained, said the US National Security Adviser Susan Rice, who welcomed the new agreement and announced the latest update.
"That's the new commitment, and one that we very much welcome," Rce noted.
Yet, no official confirmation has been received by the Turkish authorities on this either.
