The Brevard County Fire Rescue is fighting a "heavily involved structure" fire in Merritt Island early Friday morning.

Firefighters have been working on this fire for hours now.

When they first arrived they said the medium-sized home, which is sandwiched between larger homes, was heavily involved and it was hard to access.

In a tweet, the BCF also stated that it was not known if anyone was living in the home that is on South Tropical Trail, which is closed. Brevard County Fire Rescue says it has emergency vehicles blocking South Tropical Trail.

The fire company tweeted to Spectrum News 13 reporter Jerry Hume that the cause of the fire is unknown.

Check back for updates.

The location of the home is not known at this time.
