In a step reflecting the depth of diplomatic ties between the two neighboring countries, Tehran sent an official letter of thanks to Prime Minister Ali Al-Zaidi, following a joint understanding to allow forty daily flights. This stance came in a statement issued by the Iranian Embassy in the Iraqi capital on the occasion of Sovereignty Day, where it extended congratulations to the government and people of Iraq, appreciating the significant role and continuous support provided by the Prime Minister to follow up on operating this number of flights for Iranian airlines through Al-Najaf Al-Ashraf International Airport. The diplomatic mission expressed hope at the end of its statement that bilateral relations will witness further development and growth to serve the common interests of the two friendly peoples in various fields.
