President Trump threatened to "devastate Turkey economically" if the country attacks Syrian Kurdish forces in a series of Sunday evening tweets, adding that he has also asked the Kurds not to provoke the NATO ally.

"Starting the long overdue pullout from Syria while hitting the little remaining ISIS territorial caliphate hard, and from many directions. Will attack again from existing nearby base if it reforms. Will devastate Turkey economically if they hit Kurds. Create 20 mile safe zone. Likewise, do not want the Kurds to provoke Turkey."

The details: This comes of the heels of growing diplomatic tensions in the Middle East amid Trump's demand for an immediate and complete withdrawal of U.S. forces from Syria. As the Washington Post reports, the president's sudden decision "increased the possibility of a military confrontation between Turkey and Kurdish forces."
