Supporting Kurd forces is a major cause of conflict between Turkey & United States & now US is creating a new strong Kurd militia on the name of "border force" inside Syria. This US-backed militia will consist of 30,000 fighters. Turkey is already angry on the US support of Kurd armed groups & as now Turkey was going to start it's new operation against Kurd enclave of Afrin with Turkey's border inside Syria, US backed Kurd groups announce their counter plan for new strong border force of 30k fighters. US is supplying ammo to Kurd forces & also supported their war against ISIS through US led air coalition. There are also reports that recently US just supplied the anti-tank missiles to Kurd militia amid Turkey's upcoming operation & these weapons already reached to Afrin through the areas held by Pro-Assad Syrian forces.

Turkish president Erdogan has directly warned US to stop creating Anti-Turk forces in Syria & threatened to destroy these force calling them as "terror army". Turk president also warned US to remove their badges & flags from Kurd militias uniforms otherwise Turk army will bury them with fighters dead bodies. Erdogan has already announced that operation is going to start in Afrin, Manbij & in other Kurd held areas in Syria as soon as possible & Turkey will eliminate whole new US-backed force before even it's born. Turkey has started airstrikes in Afrin enclave & destroying YPG headquarters & other military sites. I will try to update on possible US reaction on Erdogan's recent warnings.
