The meeting has been called by France as president of the Security Council for August, sources from several countries said, speaking on condition of anonymity because no official announcement has yet been made. Diplomats, speaking on condition of anonymity, said it was not yet sure that Russia and China, which have vetoed three council resolutions on Syria, would attend at ministerial level.
