Russia said on Monday it would not permit a no-fly zone to be implemented over Syria, following reports that plans for such a measure were being drawn up by the United States. \"We saw with the example of Libya how such a zone is introduced and how such decisions are implemented. We do not want a repeat of this in respect to the Syria conflict. I think that we will not permit in principle such a scenario,\" Russian foreign ministry spokesman Alexander Lukashevich told reporters.
