US Secretary of State Mike Pompeo said Tuesday it was too early to know if an accord to end Turkey's assault in Syria would succeed, ahead of a deadline for Kurdish fighters to leave border areas.
"Some progress has certainly been made," Pompeo said at the Heritage Foundation in Washington hours before the 1900 GMT deadline for formerly US-allied Kurdish fighters to pull out.
But he added: "It is a complicated story, to be sure. The success of the outcome there is not yet fully determined."
