联合国特使：恢复和谈对叙利亚来说是关键时刻

U.N. envoy for Syria Staffan de Mistura said despite some concerns about recent violence, he believes "a moment of truth has arrived" as he prepared to launch a new round of peace talks aimed at ending nearly seven years of fighting.

The U.N.-led talks in Geneva due to begin Tuesday are the eighth round since 2012. Many of the prior attempts quickly fell apart amid major disagreements between the Syrian government and rebel delegations, including about whether President Bashar al-Assad should remain in office.

The two sides appear to be in the same position after opposition delegation chief Nasr Hariri told reporters Monday that their goal is for Assad to not be in power when a political transition begins.

The government delegation did not arrive in Geneva on Monday, but de Mistura planned to go ahead Tuesday with meetings with opposition figures. Prior rounds of peace talks have proceeded under similar circumstances with one party arriving a day or two late.

De Mistura said he believes it is possible for the two sides to narrow their differences as they negotiate under a framework approved by the U.N. Security Council that calls for a new constitution and elections. But he reiterated that his mediation team will not accept either side entering the talks with preconditions.
