Lavrov called on the international community "to design a road which would make sure that this issue is resolved quickly, professionally, as soon as [is] practical."
Meanwhile, in Stockholm on Friday, the head of the U.N. chemical weapons inspection team said he will deliver his report on Syria to U.N. Secretary-General Ban Ki-moon in this weekend.
Speaking by telephone from the Netherlands, Ake Sellstrom told The Associated Press he didn't know exactly when the report would be released publicly.
"It's done," Sellstrom said, "but when to present it is up to the secretary-general."
In a later conversation, Sellstrom said he wasn't quite finished with the report and that what he meant earlier was that it would be done once he delivers it to Ban over the weekend.
"I was being ambiguous on purpose," Sellstrom said.
He would not comment on the report's conclusions.
Sellstrom's inspection team was charged with determining if deadly agents were used in Syria -- not who was responsible.
