Syria's opposition National Coalition has pulled out of a series of international meetings in protest at what it said was the "shameful" failure to stop violence.
The coalition said it had decided not to attend a meeting of the Friends of Syria Grouping in Rome next month.
It was also turning down invitations for talks in Washington and Moscow.
