April 14- 
, located south of Baghdad, has been closed over security concerns and a row with the Kuwaiti company responsible for its passenger operations.
Najaf airport, 150 km south of the Iraqi capital, was shut on April 7 on orders from the transport ministry, causing daily losses of $100,000.
Transport Ministry spokesman Akeel Kawthar said the decision had been taken on safety grounds after the Kuwaiti company, Al Aqiq, failed to meet its contractual obligations to provide security equipment at the hub.
