联合国叙利亚问题特使德米斯图拉目前在叙利亚，他星期二将与叙利亚官员就本星期实施停火问题举行会谈。
德米斯图拉星期一晚间抵达叙利亚首都大马士革，这次访问事先并未宣布。
世界诸强国上星期就停止叙利亚境内的敌对活动达成一致，停火定于星期五开始，以便运送亟需的人道救援物资。
国际间希望实施停火有助于恢复叙利亚和谈。本月早些时候，叙利亚和谈在日内瓦只进行了3天即告破裂。
此后，叙利亚境内的暴力没有缓和的迹象。叙利亚政府继续在俄罗斯空袭的支援下发动攻势。各派反政府武装组织也继续在叙利亚战斗，每个组织都有不同的目标和外国支持者。
世界诸强国表示，希望在本月底之前恢复和谈。
U.N. envoy for Syria Staffan de Mistura is in Syria where he is due to hold talks Tuesday with officials on implementing a cease-fire this week.
He arrived late Monday in the Syrian capital, Damascus, for the unannounced visit.
World powers agreed last week to a cessation of hostilities, set to begin Friday, in order to let badly needed humanitarian aid be delivered.
The cease-fire is meant to help make it possible to resume international peace talks that collapsed earlier this month in Geneva after just three days.
Since then, the violence has shown no signs of letting up. The Syrian government has continued an offensive backed by Russian airstrikes. A wide array of rebel groups also continue to fight in the country, each with different objectives and international backers.
World powers have said they hope to resume peace talks by the end of the month.
