The sanctions limit the number of planes it can use at a time that it is more dependent than ever on its own resources as a result of the boycot and the refusal of international insurers to do business with Iran, Senior fellow at Nanyang Technological University's S. Rajaratnam School of International Studies, James M. Dorsey told Trend.
According to recent news, the U.S. Treasury Department has blacklisted 117 Iranian aircrafts, and imposed sanctions on them. The move comes in the wake of reports that they were being used for transfer of military personnel and weapons to Syria to crush the uprising there.
In a statement the US Treasury Department said that the move would make it easier to track the blocked aircraft and make it more difficult for Iran to use deceptive practices to try to evade sanctions.
"It means a further tightening of sanctions," Dorsey noted, explaining the move on banning Iranian planes.
He also added that there probably is Iranian Revolutionary Guard presence in Syria, however it is limited.
Iran on its part has been denying its military presence in Syria.
"Iran is engaged in an effort to mediate a ceasefire and a political process," Dorsey said. "It is probably too late for that, but an Assad regime that survives only in a rump of Syria has significantly reduced benefit to Iran."
Tehran is forbidden from selling weapons under a U.N. arms embargo, which is part of broader sanctions against Iran over its nuclear program.
However the Security Council has not taken any action on that recommendation. The U.N. panel's reports have described Iranian arms shipments to Syria via Turkey and not Iraq.
Turkey on its part has denied the reports about Iran supplying Syria with weapons.
Anti-government protests have continued in Syria for a year and half. According to UN, the total number of victims of the conflict in Syria is nearing 20,000.
More than 230,000 have become refugees with around three million in need of humanitarian assistance. The Syrian authorities say they oppose the well-armed militants.
"Turkey is not supplying weapons to neighboring countries and is not closing eye on supplying of weapons across its territory to neighboring countries," source in the Turkish Foreign Ministry told Trend.
According to the source, Turkey has clear policy with relation to neighboring countries and official Ankara does not intend to break it.
