U.S. officials don’t want to publish the details of the recently negotiated Syria cease-fire for fear of undermining the agreement, according to the State Department.

“There’s a lot of would-be spoilers out there who want to bring this deal and take it apart and make it fail,” State Department spokesman Mark Toner told reporters on Tuesday. “It’s still our assessment that we don’t want to share this thing publicly, but that assessment is ongoing.”
