At the same time, Trump urged the Kurd-dominated Syrian Democratic Forces (SDF), which the United States trained and armed for years, not to "provoke" Turkey.
Trump also said Washington would "economically devastate" Turkey if Ankara chose to strike against the US -backed YPG militants in the region. Turkish President Tayyip Erdogan called those comments "a serious mistake".
On Saturday, US Secretary of State Mike Pompeo said he was optimistic Syrian Kurds could be protected while also assuring Turkey of its right to defend itself against what it sees as terrorists.
US President Donald Trump stated on Twitter that the United States have defeated the IS forces in Syria, which is the only reason for the US troops being there. On Friday, the US-led coalition said it had started the pullout, but officials later said it involved only equipment, not troops.
Meanwhile, Presidency Communications Director Fahrettin Altun said Turkey has no problems with the Kurds and that its problem is with the PKK terrorist organization and its Syrian extensions. "We will protect Kurds and other Syrians against all terrorist threats", Kalın added. Without giving any further details, he wrote "Create 20 mile (32 kilometers) safe zone".
In an apparent gesture to save face, following a questionable outcome of four years of uninvited American presence in Syria and an abrupt withdrawal, Trump has once-again credited the USA military for destroying IS, disregarding the fact that most of the country was liberated from terrorists by the Syrian army, with the help of the Russian military. "Will attack again from existing nearby base if it reforms", Trump said on Twitter.

For the president, who visited the Texas border with Mexico on Thursday , the border situation amounts to an invasion by criminals.
"Russia, Iran, and Syria have been the biggest beneficiaries of the long-term US policy of destroying ISIS in Syria - natural enemies", he tweeted. "Stop the ENDLESS WARS!" Will devastate Turkey economically if they hit Kurds.
"If the (pullout) is put off with ridiculous excuses like Turks are massacring Kurds, which do not reflect the reality, we will implement this decision", Turkish Foreign Minister Mevlut Cavusoglu said on Thursday, adding that the fight against the YPG does not depend on "anybody's permission".
Trump's decision to call back USA troops in Syria, who were first deployed in 2015, was followed a day later by the resignation of Defense Secretary Jim Mattis, who wrote a letter to the president saying he had the right to have a secretary of defense "whose views are better aligned with yours".
"There is no difference between DAESH [Islamic State], PKK, PYD and YPG".
Erdogan's communications director Fahrettin Altun said "Turkey will continue its anti-terror fight decisively" and that it was a protector of the Kurds, not their enemy.
