Iranian Foreign Ministry Spokesman Ramin Mehmanparast has criticized Iraq for inspecting an Iranian plane taking humanitarian aid to Syria.
Mehmanparast made the remarks on Tuesday, saying that the move is a violation of international law.
However, he noted that the inspection of Iranian planes has disproved the claim that Iran is sending arms to Syria.
Mehmanparast said Iran will continue relief operations in Syria despite the inspections.
Since mid-March 2011, Syria has been experiencing a deadly unrest, which has killed many people including large numbers of security personnel.
The prolonged violence in the Arab country has forced many of its citizens, including Palestinian refugees in the country, to migrate to neighboring states such as Lebanon.
According to the United Nations High Commissioner for Refugees (UNHCR), there are over 270,000 registered Syrian refugees in Lebanon while more than 143,000 others are awaiting registration.
The Syrian government says the chaos is being orchestrated from outside the country, and certain Western states and their regional allies such as Qatar, Saudi Arabia, and Turkey, have been trying to fuel the turmoil.
