Six airlines, from the United Arab Emirates, Turkey and Lebanon, suspended flights to Baghdad on Tuesday after bullets hit an airplane operated by budget carrier Dubai Aviation Corp., known as flydubai, as it was landing at Baghdad airport.

Iraqi Transport Minister Bayan Jaboor said the plane was hit at an altitude of 600 meters (2,000 feet) by gunfire from what he judged was a light machinegun.

He did not rule out that Monday's shooting could be a militant action but said security forces had identified the source.
