The blaze at Tan Son Nhat Airport in Ho Chi Minh City broke out early on Monday morning inside the terminal building.

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 immediately clear.

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

'The domestic terminal has been temporarily closed as from 05:00 am local time Monday (2200 GMT, 6am Singapore time)', said the 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. -- AFP
