Iran has urged Iraq to lift restrictions on flights between the two countries amid disruptions linked to United States sanctions on Iranian aviation.
The restrictions have affected passengers travelling between Iran and Iraq, including pilgrims, patients, students and business travellers.
Iranian authorities are calling for normal air services to resume, stressing the importance of regular flights between the two neighbouring countries.
Iraq suspended some flights to and from Iran after U.S. sanctions affected Iranian airlines and aviation-related services.
However, limited flights have resumed under a special arrangement, including services connecting Iran with the Iraqi city of Najaf.
The disruption comes as Iraq seeks to maintain its air links with Iran while navigating the impact of U.S. sanctions.
The flight restrictions are particularly significant because of the strong religious, cultural and economic ties between Iran and Iraq.
Thousands of Iranian pilgrims regularly travel to Iraqi cities, including Najaf and Karbala.
Iran says restoring air connections would ease difficulties for travellers and support the movement of people between the two countries.
Tehran is therefore urging Baghdad to remove the remaining restrictions and restore regular flights.
The issue remains part of wider tensions surrounding U.S. sanctions on Iran and their effect on countries and businesses that maintain transport and economic links with Tehran.
