A statement released by the Southern Airport Authority said firefighters battled for two hours to bring the fire under control.

Pictures broadcast on the state-run Vietnamese Television network showed a blackened terminal building with several broken windows, but the full extent of the damage was not clear.

No one was injured in the fire but operations at the airport were disrupted.

"The domestic terminal has been temporarily closed as from 5am local time Monday (0900 AEDT)," the airport authority said in a statement.

"Services will continue as normal... with domestic flights operating out of the international terminal."

The statement added that officials were working to asses the extent of the damage.

The official announcement did not give a reason for the fire but an AFP source at the airport said a wiring fault was thought to be the cause.
