“The agreement is basically broadly holding, quite well. In all agreements there is a period of adjustment, we are watching very carefully, but we can say we believe it has fairly good chances of working out” – said  U.N. envoy Staffan de Mistura told a news conference on Syria.

Agreements to de-escalate the fighting  could simplify the conflict and lead to a phase of stabilizing the country, but such deals must be an interim measure and avoid partition, de Mistura suggested.

Addressing the start of five days of peace talks in Geneva, de Mistura told the discussions were taking place in Amman to monitor implementation of a U.S.-Russian imposed ceasefire for southwest Syria, the first peacemaking effort of the war by the U.S. government under President Donald Trump.
