UN-Arab League envoy Kofi Annan is finalizing plans to return to Syria for talks aimed at revitalizing the cease-fire and peace process he brokered last month.
Annan's spokesman Ahmad Fawzi said the exact dates of Annan's Damascus trip have not yet been determined.
One of Annan's deputies returned from Syria on May 24 after talks with all parties involved in the violence.
On May 25, army tanks were deployed for the first time in Syria's second-largest city, Aleppo, after tens of thousands of people demonstrated against President Bashar al-Assad's regime.
Earlier, troops earlier shot dead at least one civilian in Aleppo.
About three dozen others were killed in clashes across the country on May 25.
It is estimated that more than 9,000 people have died since the antigovernment uprising began in the spring of 2011.
