The United States and Russia agreed that the Syrian cessation of hostilities that began on Monday had largely held and should be extended for another 48 hours despite sporadic violence, the U.S. State Department said on Wednesday.

The cessation of hostilities, brokered by U.S. Secretary of State John Kerry and Russian Foreign Minister Sergey Lavrov on Friday, went into effect on Monday night.

State Department spokesman Mark Toner said Kerry and Lavrov had spoken by telephone earlier on Wednesday and agreed it was worth extending the truce.
