US Defense Secretary Patrick Shanahan and Joint Chiefs of Staff Chairman Joseph Dunford will host their Turkish counterparts in Washington on Friday, White House spokeswoman Sarah Sanders said, according to the Washington Post.
The White House said Trump and Turkish President Recap Tayyip Erdogan, by telephone, yesterday "agreed to continue coordination on the establishment of a possible buffer zone."
In a related context, the Wall Street Journal reported that the United States has decided to keep 200 US troops for an unlimited period of peacekeeping in Syria.
Both France and Britain, part of the Global Coalition against IS, did not immediately respond to the United States' announcement today.
The newspaper quoted yesterday, according to US officials, the refusal of America's closest European allies to ask the Trump administration to bridge the gap, and a senior administration official said the Allies told the United States that "will not stay if the last withdrew."
The full withdrawal was expected by the end of April, as defense officials, lawmakers and some White House aides expressed concern that tens of thousands of armed fighters were still scattered throughout Syria and Iraq.
