Syria Cease-Fire: 'Provisional Agreement' Reached, John Kerry Says

AMMAN, Jordan — Secretary of State John Kerry says a "provisional agreement" has been reached on a cease-fire in Syria's five-year civil war.

Kerry, who spoke Sunday alongside Jordanian Foreign Minister Nasser Judeh in Amman, Jordan, said he had spoken earlier that morning with his Russian counterpart, Sergey Lavrov, about the agreement. Now, he said, both the U.S. and Russia planned to reach out to the various sides of the conflict.

Kerry said he hoped President Barack Obama and Russian President Vladimir Putin would talk soon and that hopefully, after that, implementation could begin.

Kerry said details of a cease-fire still need to be resolved, such as enforcement.

Kerry said not every party will necessarily agree automatically, but said "There is a stark choice for everybody here."

U.N. Secretary-General Ban Ki-moon warned last week it would be "extremely difficult" to monitor any deal. Any cease-fire would not apply to U.N.-designated terror groups, which include ISIS and the al-Nusra Front.
