Iraqi authorities have forced another Syria-bound Iranian plane to land in Baghdad for inspection, despite Tehran's repeated protests against the move, Press TV reported.
Iraqi civil aviation authorities forced a cargo plane belonging to Iran's Caspian Airlines to land at Baghdad International Airport, the Iraqi Transport Ministry said in a statement on Monday, Aswat al-Iraq reported.
The plane was searched by security forces at the airport, but nothing illegal was found and the plane was allowed to continue its flight, the statement added.
Tehran has repeatedly criticized Iraqi officials over the inspection of Iranian planes carrying humanitarian aid to crisis-hit Syria.
It says the inspections - which have invariably failed to find any illegal cargo - are carried out under political pressure from other countries.
"This measure is not negligible or justifiable, and we have voiced our protest against this approach and consider it a violation of international law and conventions," former Iranian Foreign Ministry Spokesman Ramin Mehmanparast said on April 23.
He added that Iraqi officials had been previously warned against insisting on the inspection of Iranian airplanes.
