The National Fire Authority is yet to establish the cause of two house fires over the weekend.

The first incident occurred on Saturday at Rice Mill Road, Votualevu, Nadi where a home belonging to a 51-year-old man was destroyed in a fire.

Police say the man and his family were away when the incident occurred.

They say the estimated cost of damage is $30,000.

The second fire incident occurred at Crompton Place in Samabula at around 2 am yesterday.

The occupants of the house were sleeping when they were awoken by cracking noise and saw that smoke and fire had engulfed the hallway.
