Hours after Cavusoglu's statement, US Vice President Mike Pence warned Ankara against purchasing Russian anti-missile systems that Washington considers a threat to US military equipment.
"Turkey must choose. Does it want to remain a critical partner in the most successful military alliance in history or does it want to risk the security of that partnership by making such reckless decisions that undermine our alliance?" Pence said in remarks at a NATO event in Washington.
A State Department official told Sputnik on Monday that the US government warned Ankara that it could face even more consequences including sanctions for purchasing Russian S-400 systems.
