叙利亚总统阿萨德向俄罗斯总统普京证实，叙利亚愿意帮助落实预定星期六生效的停火协议。
Syrian President Bashar al-Assad confirmed to his Russian counterpart Vladimir Putin that Syria is ready to help implement a cease-fire planned to begin on Saturday.
这两位领导人星期三进行了电话交谈，强调继续打击恐怖组织伊斯兰国组织和努斯拉阵线的重要性。美国和俄罗斯建议结束敌对状态的协议不包括这些激进分子。
The two leaders spoke by telephone Wednesday and highlighted the importance of continuing to fight terror groups such as Islamic State and Jabhat al-Nusra. The militants are not part of a U.S.-Russian proposal for a cessation of hostilities.
其他团体要在星期五之前表明是否参加停火。
Other groups are supposed to say by Friday whether they are taking part.
叙利亚主要反对派高级谈判委员会说，他们参加停火的先决条件是，运送人道主义援助并结束对平民的围困和空袭。
The main opposition High Negotiations Committee has said its participation is contingent on the delivery of humanitarian aid and the end of sieges and airstrikes against civilians.
俄罗斯国际文传电讯社引述俄罗斯外交部发言人佩斯科夫的话说，俄罗斯关注的重点是叙利亚停火，现在谈论任何备选计划还为时过早。
Russia's Interfax news agency quoted Foreign Ministry spokesman Dmitry Peskov saying the cease-fire is the government's main focus in Syria and that it is premature to talk about any backup plan.
