A UN mission to investigate alleged use of chemical weapons in Syria's civil war tentatively plans to enter the country on Sunday, officials said on Friday.
The team, consisting of weapons experts from the Organization for the Prohibition of Chemical Weapons, plans to look into claims of use of sarin gas and other toxic nerve agents.
UN Secretary-General Ban Ki-moon said on Wednesday details of the trip had been worked out with the Syrian government and that the team's departure was imminent.
An official told Reuters on Friday the team would cross into Syria on Sunday, assuming security conditions permitted. A diplomat in the region confirmed the timetable.
One site to be visited by the UN experts is Khan al-Assal in Aleppo, where the Syrian government says rebels used chemical weapons in March.
Two other locations have not yet been identified and may be too dangerous for the team to visit, the official said.
