Turkey tells US at NATO that Russian defence purchase is 'done deal'
- Ankara and Washington have been at odds over issues including Syria policy, human rights and the S-400 air defence acquisition, over which the United States has sanctioned Turkey and removed it from its F-35 fighter jet programme.
- "On the S-400s, we reminded them once again why Turkey had to buy them, and repeated that Turkey had bought them and this is a done deal," Cavusoglu told.
