A fire appliance was spotted at the scene of the blaze at the Kahana Lagoon resort.

Unconfirmed reports said there were indications that a person got stuck inside the restaurant at the time of the incident.

It was alleged that there was a fatality.

Kaniva News was unable to confirm this.

Streamed videos taken at the scene, seen by Kaniva News, appeared to show that the spaces for the firefighters and their engines to tackle the fire effectively were quite limited.

There were also reports indicating that the fire had caused significant damage to one of the water hoses used to control the fire.

When the firefighters finally arrived at the scene, the flames had already engulfed a significant portion of the building, billowing thick clouds of smoke into the air, according to a Facebook live streamer at the scene.
