BEIRUT (AP) — A top adviser to the United Nations envoy for Syria said Tuesday that their "main guidance" for the first intra-Syrian peace talks in 10 months will be a Security Council resolution that calls for political transition. According to several estimates, Syria's war has killed some 400,000 people, displaced millions and sent more than four million refugees to neighboring countries. The groups that include Human Rights Watch, Amnesty International and Physicians for Human Rights say the priorities are to end unlawful attacks and to ensure aid access and safe passage for fleeing civilians, detainee rights, justice, and security sector reform.
