Turkey’s deputy prime minister ravished the leader of the free world for backing Syrian Kurdish YPG forces, which Turkey has deemed a terror organisation.
Numan Kurtulmus said: “There has never been an incident where a group in the Middle East has been armed, and they returned the weapons.
“[The United States] have formed more than a terrorist organisation there, they formed a small-scale army."
Turkish president Recep Erdogan also warned that Turkey is ready to intervene militarily in north Syria to repel Syrian Kurdish forces.
Turkey have long branded the YPG as a "terrorist" group, although it forms a major part of the US coalition campaign to capture ISIS’ stronghold of Raqqa, Syria.
Ankara officials denigrate the YPG insisting they represent a security threat.
They see it as an extension of the Kurdistan Workers Party (PKK), which has been fighting an insurgency against the Turkish state for decades, according to reports.
Tensions flared between the US and Turkey after US officials told Reuters last month, weapons provided to the YPG will be taken back once ISIS was defeated.
But US Defence Secretary Jim Mattis has left the possibility of longer-term assistance to the YPG claiming they may need further artillery for the future.
Mr Mattis said: “We'll be recovering (the weapons) during the battle, repairing them.
“When they don't need certain things anymore, we'll replace those with something they do need.”
Turkish president Erdogan reportedly echoed Mr Kurtulmus comments, calling the US a sponsor of the “terrorist” YPG group.
Speaking ahead of the G20 leaders summit in Hamburg later this week, he drew further tensions with the US, siding with Qatar over its dispute with other Arab states.
Blasting their 13-point demands as unacceptable, Erdogan told France 24: “When it comes to this list of 13 items ... it's not acceptable under any circumstances.”
He added: “We remain loyal to our agreement with Qatar. If it requests us to leave, we will not stay where we are not wanted.”
