Syria's opposition National Coalition has announced it is pulling out of scheduled talks in Russia and the United States, as well as next month's Friends of Syria meeting in Rome.
The Coalition statement said, "The international silence on the crimes committed every day against our people amounts to participating in two years of killings".
