"Today we started a discussion of the topic of fighting terrorism from the four baskets. We believe that this meaningful discussion with de Mistura is an important start," Ambassador to the UN Bashar Jaafari told reporters.
Since 2011, Syria has been engulfed in a civil war, with government forces fighting against numerous opposition and terrorist groups, including al-Nusra Front and Daesh, banned in a range of countries, including Russia.
"My experts, a group of Syrian legal experts, today began a discussion with de Mistura's team on the principles of a political settlement. This is the first time our experts meet on both sides," Jaafari told reporters.
A draft constitution comprising 12 key articles is on the agenda, Jaafari specified.
