June 3 (UPI) -- Kuwait closed its main airport in Kuwait City on Wednesday after Iranian missile and drone strikes injured several people and caused "significant damage" to its main terminal building as renewed hostilities between the Iran and the United States escalated.

The airport activated its emergency plan, suspending all flights indefinitely after its Terminal 1 building was the target of "Iranian aggression, resulting in significant damage to several airport facilities, in addition to recording human injuries," the Directorate General of Civil Aviation said in an update on X.

DGCA spokesman Abdullah Al-Rajhi said it has been decided to suspend air traffic and divert flights to alternative airports until further notice pending the completion of repair work to enable the airport to resume operations, saying that inspection and comprehensive assessment by technical and specialized teams was already underway.
