Republican lawmakers in both chambers of the US Congress have announced plans to impose sanctions against Turkey over its military offensive against the Kurds.
Both Turkey and the Kurds in northern Syria are US allies; however, the two sides express deep animosity towards one another.
To make the situation between the two Washington allies worse, US President Donald Trump green-lighted Turkey's long-due demand for a military offensive against Kurds in northern Syria.
Republican US Senator Lindsey Graham blasted Trump on Wednesday for his decision to turn his back on the Kurds.
Graham described Trump's decision as granting Turkey US' permission to invade northern Syria and potentially wipe out US-backed Kurdish fighters.
Meanwhile, the US Republican top representative Liz Cheney warned Turkey on Thursday that Ankara should refrain form the attack on the Kurds, saying such an attacs would have serious consequences.
"President (Recep Tayyip) Erdogan and his regime must face serious consequences for mercilessly attacking our Kurdish allies in northern Syria," said Cheney, who is chairperson of the House Republican Conference.
In a similar move, the Iranian Foreign Ministry called on Turkey to "immediately" stop its military campaign in northeastern Syria.
“The dire humanitarian situation and the dangers posed to civilians in the conflict area” call for “the immediate cessation of attacks and the withdrawal of Turkish troops from Syria,” the Iranian Foreign Ministry said in a statement on Saturday.
Iran, while realizing Turkey's security concerns, urged mildness in northern Syria,
The foreign ministry condemned Turkey's military campaign in Syria as a deadly offensive that would bring about “widespread human and material damage”.
Tehran has voiced readiness to play the role of a mediator to de-escalate tensions between Turkey and Syria, it said.
The ministry insisted that “peaceful measures and respecting Syria's sovereignty and territorial integrity” were the sole way to de-escalation of tensions.
